fiddling around with the testscript.tcsh, currently have:

#!/bin/tcsh

set ARG = $1

echo $ARG

find ~ -name "*ARG*" -print

used this command: ./testscript.tcsh .txt

got this output: /home/leal/PhysHonr268n/homesearch_ARG.txt

wondering how to get it to display all files with the given argument

deleted the above file cause it was just an empty file and now, my script is running but not returning any files

after some tweaking with Avi, changed last line of script to: 

find . "*$ARG*" -print

with this command: ./testscript.tcsh .tcsh

I now get this:

.tcsh

.

./homesearch.tcsh~

./file.txt

./file.txt~

./#file.txt#

./testscript.tcsh

./testscript.tcsh~

./testfile~

./homesearch.tcsh

./test.txt~

./searchandfind.tcsh

./#testscript.tcsh#~

./searchandfind.tcsh~

find: `*.tcsh*': No such file or directory

not sure why it keeps saying that it can't "find" a file or directory but also gives me everything in the current directory

g++ file_name_here compiles that file, then it appears that file stays on call to be executed(using ./a.out) until you compile something else. I wonder if i can adjust ./a.out to run something from a separate directory....

I found out

-you can compile stuff from a different directory as long as you provide the proper file path

- ~/a.out doesnt work like i thought it would(assuming the file is in ~ and im attempting to run from a subdirectory.)

-weirdly, you can run a script from a directory below you, this works(below) apparently though, I'm not sure why the '.' works, though main.cpp is in PhysHonr268n, not ~. I guess the compiler stores the compiled file in your current directory to be executed? 

[leal@hepcms-in1 ~]$ g++ ~/PhysHonr268n/main.cpp

[leal@hepcms-in1 ~]$ ./a.out

hello world

i = 2

a = 3.3

a*i = 6

...when you compile and have no errors... *explosions and confetti and champagne popping*
