In csh based scripts, I can use the 'source' keyword, or in 'sh' based scripts, I can use the '.' symbol. But what would be the equivalent in Perl ?
To simplify things, you can use the shell's "eval" command. Then you won't need to save the variables in a file.
For example:
................... $ cat env-var #!/usr/bin/perl
print "export FOO='my value'\n";
$ ./env-var export FOO='my value'
$ eval `./env-var`
$ echo $FOO my value ...................
Note that this assumes that you're not using a shell that uses csh syntax - to be portable, you'd need to have the Perl script accept an option to specify which of the two common syntaxes to use for setting variables.
