I'm in need to pass arguments to a shell script, which after validation, need to be passed on to a function in the script either as same or after modification.

#!/bin/sh
func1(){
echo "called func1 with $1" ;
exit 0 ;
}

func2(){
echo "called func2 with $1" ;
exit 0 ;
}

if [ $# -eq 0 ]
then
    echo "Usage:" ;
    echo "script.sh arg1 arg2" ;
    exit -1 ;
fi

if [ "$1" -eq "txt1" ]
then
    func1 $2 ;
    exit 0 ;
fi

if ["$1" -eq "txt2" ]
then
    func2 $2 ;
    exit 0;
fi

The response I get is 

sh script.sh txt1
sh: txt1: bad number
sh: txt1: bad number

You are using the wrong operator for string comparison. You want to use =, not -eq (which is comparing integers).

Note that [ is just an internal command of the shell, so you need to separate that with whitespace from its arguments. (At the third test in your script.)

    Might also mention the need for whitespace (missing in the second invocation). – Charles Duffy Dec 21 '15 at 20:18
  • Thanks for the quick help. I'm new to both STCK OVFL and linux shell. Also, I thought the response would help some of the newbies like me who search for the response rather than a question list? – Ananth Dec 22 '15 at 21:28
