Passing Arguments-Help

Shell Programming and Scripting
1

Hi,
I have a script which adds the user credentials to an ldap server. Im passing the variables as below..

/path/my_script $uname $pwd $environ ${deposit}

If i enter some special characters like ';' in $pwd, script returns an error which is set to display if the user enters insufficient arguments...

i will explain it with an eg:

uname=john
pwd=qwerty;123
environ=student
deposit=1234

So if run

/path/my_script $uname $pwd $environ ${deposit}

itz giving an error which i have set with this condition in my_script

if [ $# -lt 3 ]; then
        echo "Error : Insufficient number of arguments"
        echo "Usage : $0 username password environment"
        echo "Eg : $0 s1corp D56GHxde vault"
        exit 0
fi

Can anyone plz help me to sort out this error??

Try escaping them when being entered by a preceding \ or have every value enclosed by hard single quotes like this:

str\;ing
'str;ing'

So you meant..

/path/my_script $uname '$pwd' $environ ${deposit}

Thatz not working!!??

No that will not work since the variables can't be substituted inside ' '.
So try using " " around it first.

5

the values are read from another script and passed over here.. so what modifications can I make with $pwd?? thatz also not working as it is called inside a CGI script like following... :frowning:

$cmd = "sudo ssh -i /root/.ssh/id_dsa server-fe '/var/www/scripts/my_script $uname $pwd $environ ${deposit}'";

so if i put

$cmd = "sudo ssh -i /root/.ssh/id_dsa server-fe '/var/www/scripts/my_script $uname "$pwd" $environ ${deposit}'";

itz showing internal server error....

Basically from shell script to shell script:

root@isau02:/data/tmp/testfeld> cat script1.ksh
VAR='abc;123'

./script2.ksh "${VAR}"

root@isau02:/data/tmp/testfeld> cat script2.ksh
echo "$1"

root@isau02:/data/tmp/testfeld> ./script1.ksh
abc;123
