Shkrimi i skripteve ne Bash Shell
Disa rregulla te pergjithshme
1- Skripti duhet te filloje me
#!/bin/bash
ne menyre qe te percaktoje cilin shell do te perdorim per skriptin.
2- Komentet dhe komandat zgjasin vetem nje rresht
3- Komentet fillojne me #
4- Komandat mund te vendosen ne kllapa
Shembull i nje skripti
#!/bin/bash
# ky skript realizon nje pershendetjee
echo pershendetje nga skripti
Eshte e mundur qe te krijojme nje variabel ne skript dhe ti japim atij nje vlere, per shembull
Sintaksa
variable=$(shprehja qe i jep vlere vairablit)
psh
date_formatted=$(date +%m_%d_%y-%H.%M.%S)
Skripti me poshte
#!/bin/bash
#this will copy a file, appending the date and time
# to the end of the file name
date_formatted=$(date +%m_%d_%y-%H.%M.%S)
echo "Koha e formatuar eshte:" $date_formatted
do te shfaqte
student@ubuntu:~/bin$ sudo ./datecp
Koha e formatuar eshte: 04_08_13-18.24.15
Ne shembullin me poshte do te ndertojme nje skript qe merr si argument nje skedar dhe nje emer te ri per te. Skripti do te kopjoje skederin 1 me emrin skedar 2 dhe do ti shtoje emrit te ketij te fundit kohen ku u krye veprimi si nje prapashtese
#!/bin/bash
#this will copy a file, appending the date and time
# to the end of the file name
date_formatted=$(date +%m_%d_%y-%H.%M.%S)
echo "Koha e formatuar eshte:" $date_formatted
cp -i -v $1 $2.$date_formatted
Skripti duhet therritur me dy argumentat ($1 dhe $2)
student@ubuntu:~/bin$ sudo ./datecp datecp datecp
Koha e formatuar eshte: 04_08_13-18.35.42
`datecp' -> `datecp.04_08_13-18.35.42'
student@ubuntu:~/bin$ ls
datecp datecp.04_08_13-18.35.42 soft.04_08_13-18.27.24
student@ubuntu:~/bin$
Komanda cp kopjon nje skedar.
Opsioni -i = interactive , nese skedari i ri ekziston na pyet nese duam te mbivendosim.
Opsioni -v = verbose, sqaron veprimin qe po kryhet
Shembulli me poshte ilustron leximin e nje skedari rreshte per rresht dhe afishimin e tij duke shtuar nje numerues ne fillim te rreshtit
#!/bin/sh
fname=ict
# exec<$fname >$1
value=0
while read line
do
value=`expr $value + 1`;
echo $value $line;
done < $fname
echo "****$value";
