I am attempting to write what I thought would be a simple wrapper
script around ldapmodify that would allow me to easily reset a user's
password. Inside my bash based wrapper script is a single line of perl
that encrypts the password I input and returns it as a specially formatted
string that then gets output to a LDIF file that is eventually sourced by
ldapmodify.
Then I wanted to be able to run the resulting script by doing:
reset_password george newpasswd
to reset the password in ldap to newpasswd for user account george
My problem is I want to be able to pick up $2 from the command line invocation
of my bash script for the desired password and then pass that into the one line
perl piece. But with all of the single quotes, double quotes, back ticks and
etc. I am not able to get the password value in the $2 to be correctly passed
into the perl one line part of the bash script.
The core part of the script I am having a problem with looks like:
#!/bin/bash
OPASS=$2
PASS=`perl -e 'print("userPassword:
{CRYPT}".crypt("$OPASS","frat-salt")."\n");'`
The actual value of $PASS is supposed to end up looking like:
userPassword: {CRYPT}frJTbxR6L.kgA
I have looked at doing something like this:
#!/bin/bash
perl << 'EOF'
print("userPassword: {CRYPT}".crypt("$OPASS","frat-salt")."\n");
EOF
but I still don't think the bash variable OPASS would get properly evaluated in
the perl invocation.
Any ideas?

Stuff inside of single quotes won't have variables expanded:
shu...@edwin:~$ OPASS=test
shu...@edwin:~$ echo "$OPASS"
test
shu...@edwin:~$ echo '$OPASS'
$OPASS
shu...@edwin:~$
So you need to have the -e argument surrounded by double-quotes. I don't
know if the perl code will allow you to use single quotes in place of
double quotes or not. If it does, then maybe use single quotes there for
readability. Otherwise, and in the case of the $OPASS parameter, you'll
need to escape the double quotes individually, as in:
PASS=`perl -e "print(\"userPassword:
{CRYPT}\".crypt(\"$OPASS\",\"frat-salt\").\"\n\");'`
A bit messy, but I think it would work. ;)
