Run Script Linux

Scripts are also identified with a shebang. Shebang is a combination of bash # and bang ! followed the the bash shell path. This is the first line of the script. Shebang tells the shell to execute it via bash shell. Shebang is simply an absolute path to the bash interpreter.

Docker provides a convenience script at _in_new to install Docker intodevelopment environments non-interactively. The convenience script isn'trecommended for production environments, but it's useful for creating aprovisioning script tailored to your needs. Also refer to theinstall using the repository steps to learnabout installation steps to install using the package repository. The source codefor the script is open source, and you can find it in thedocker-install repository on GitHubopen_in_new.

The installation script requires root or sudo privileges to install anduse Docker. If you want to grant non-root users access to Docker, refer to thepost-installation steps for Linux.You can also install Docker without root privileges, or configured to run inrootless mode. For instructions on running Docker in rootless mode, refer torun the Docker daemon as a non-root user (rootless mode).

Docker also provides a convenience script at _in_new to install pre-releases ofDocker on Linux. This script is equal to the script at get.docker.com, butconfigures your package manager to use the test channel of the Docker packagerepository. The test channel includes both stable and pre-releases (betaversions, release-candidates) of Docker. Use this script to get early access tonew releases, and to evaluate them in a testing environment before they'rereleased as stable.

If you installed Docker using the convenience script, you should upgrade Dockerusing your package manager directly. There's no advantage to re-running theconvenience script. Re-running it can cause issues if it attempts to re-installrepositories which already exist on the host machine.

script command in Linux is used to make typescript or record all the terminal activities. After executing the script command it starts recording everything printed on the screen including the inputs and outputs until exit. By default, all the terminal information is saved in the file typescript , if no argument is given. script is mostly used when we want to capture the output of a command or a set of command while installing a program or the logs generated on the terminal while compiling an opensource codes, etc. script command uses two files i.e. one for the terminal output and other for the timing information.

Example 1: To start a typescript without any argument. If no filename is given as argument, script will automatically create a file namely typescript in the home directory to save the recorded information.

Be aware that the +x on some systems in /tmp may not work as some standards are to not allow executables in /tmp. You could just use /bin/sh directly to run the shell script without marking it executable.

OK ! I have faced most likely same issue but have solved it by splitting fixlet in 2 actions, one for downloading files on endpoints with BIGFIX action script & 2nd action to run shell script with SH action script, and removed the default action for both of them so user can see both action while taking take action & use accordingly.

Mine script is different but case is very much similer to it, we were trying to copy some file on endpoints & then executing a specific script which suppose to drop the output in a file somehow script was running perfectly fine but not creating output file, tried many ways to run it but could not helped hence I split the task into 2 action as described above & amazingly script part running fine under sh action script & generating output with same command which we were trying to run in BIGFIX action script.

/etc/init.d/criodaq start (criodaq is the name of the script and cRioTestC is a C binary). I know the program starts because I have programmed LEDs on the chasis but nothing prints in the console. Is there a way in the script to either log print statements from the program running or show in console?

To log files I had to remove --background from my script and add > /home/admin/cRioKE/criodaqlog.log 2>&1 Code below. I realise this is a 1) a bit dirty and 2) I don't fully understand what the consequences of removing --background might be?

The SystemExec VI is a bit of a special case, it basically does things to hijack the standard output. You can probably get around this by adding a layer: have a script that, within the script, will call the binary and redirect stdout to a log file. Not 100% sure this will work, but I know that trying to take stdout from the System Exec.vi is unlikely to do what you want

The only issue I am having is trying to configure the serial port settings at boot. This is a slightly different use case from the above, since I don't want to start a daemon, but simply run a few commands. I use stty to set my serial configurations, and have incorporated it into the startup script as shown below.

Now, if I test this after installing the script (by entering "/etc/init.d/ser2net.startup start" in the shell), this works fine. However, if I reboot, the commands seem to do nothing, and the port config stays default.

I installed MATLAB R2022a in my new Arch system, it works well in command window (MATLAB command line). But when I tried to open or create a script file, a dialog appear with Unable to open this file in the current system configuration, and the command line outputs error message as below

I have been using Matlab for many years and problems come almost with every new version or after some system update (actualisation glibc to version 2.35, e.g.). Some advice can be found at Arch Linux Wiki. If you need normal Matlab script (sequence of commands) you can create it in any normal text editor (nano, pico, mcedit, gedit, etc., not libreoffice writer or something like it). You lost the possibility of easy debugging, of course.

Update: The need for system's "native" shell script is that it needs to pick the right interpreter version, conform to certain well-known environment variables etc. Installing additional environments like CygWin is not preferable - I'd like to keep the concept "download & run".

Universal comments, of course, can be done with the character sequence : # or :;#. The space or semicolon are necessary because sh considers # to be part of a command name if it is not the first character of an identifier. For example, you might want to write universal comments in the first lines of your file before using the GOTO method to split your code. Then you can inform your reader of why your script is written so oddly:

Thus, some ideas and ways to accomplish sh and cmd-compatible scripts without serious side effects as far as I know (and without having cmd output '#' is not recognized as an internal or external command, operable program or batch file.).

It uses again the : trick and the multi line comment. Looks like cmd.exe (at least on windows10) works without problems with the unix style EOLs so be sure that your script is converted into linux format. (same approach has been seen used before here and here ) . Though using shebang still will produce redundant output...

Probably you'll need to use /r/n as a new line instead of a unix style.If I remember correct the unix new line is not interpreted as a new line by .bat scripts.Another way is to create an #.exe file in the path that does do nothing in similar manner as my answer here: Is it possible to embed and execute VBScript within a batch file without using a temporary file?

It is hard to retain a file which has two kinds of line breaks contained within it, that being /n for the bash part and /r/n for the windows part. Most editors try and enforce a common line break scheme by guessing what kind of file you are editing. Also most methods of transferring the file across the internet (particularly as a text or script file) will launder the line breaks, so you could start with one kind of line break and end up with the other. If you made assumptions about line breaks and then gave your script to someone else to use they might find it doesn't work for them.

One should therefore use the DOS line break of /r/n and also protect the bash script from the DOS /r by putting a comment at the end of each line (#). You also cannot use line continuations in bash because the /r will cause them to break.

The following works for me without any errors or error messages with Bash 4 and Windows 10, unlike the answers above. I name the file "whatever.cmd", do chmod +x to make it executable in linux, and make it have unix line endings (dos2unix) to keep bash quiet.

The previous answers seem to cover pretty much all the options and helped me a lot. I'm including this answer here just to demonstrate the mechanism I used to include both a Bash script and a Windows CMD script in the same file.

The first line (echo >/dev/null # >nul & GOTO WINDOWS & rem ^) will be ignored and the script will flow through each line immediately following it until the exit 0 command is executed. Once exit 0 is reached, the script execution will end, ignoring the Windows commands below it.

The downside to this is that playing with line break encoding is just asking for trouble, at least on Windows. For example, Notepad creates new line breaks based on the style of the first line break. But PowerShell ISE uses the line breaks around the modified text to determine what style to use. And even if you get everything right, some scripting platforms will re-write line breaks based on the target OS.

There is a platform independent build tools like Ant or Maven with xml syntax (based on Java).So, you could rewrite all your scripts in Ant or Maven an run them despite os type.Or you could just create Ant wrapper script, which will analyze os type and run appropriate bat or bash script. ff782bc1db
