Hi!
I'm trying to take command line args with the help of a bash script But i'm not able to achieve it Pls guide.
#!/bin/bash # i want to detect command line options # e.g. sample.sh -1 foo1 -2 foo2 -3 foo3 # then i want following : arg1=foo1, arg2=foo2 , arg3=foo3 # I tried following but arg1 takes the value $2, arg2 $3 and arg3 $3
count=0 # counter to track current command line arg
for cmd in $@ do count=`expr $count + 1` # count = count + 1 if `test $cmd = -1` then arg1=$`expr $count + 1` echo $arg1 # unfortunately it gives $2 and not foo1 fi done
