Perl command error...
Good morning!

Imtrying to run:

Code:
#!/usr/bin/perl

perl -nle 'print if /\var\/log/' /etc/syslog.conf

But I keep getting error: Do you need to predeclare -nle.Im trying to create a script that read the contents of /etc/syslog.conf and print out every line that contains /var/log.

Run the Perl one-liner on the *nix command prompt.
My file "f4" is equivalent to your "/etc/syslog.conf" in the testcase below -

Code:
$ 
$ cat f4
first line
/var/log in this line
third line
and this line also has /var/log
fifth line
sixth line
and /var/log embedded in here too
$ 
$ perl -nle 'print if /\/var\/log/' f4
/var/log in this line
and this line also has /var/log
and /var/log embedded in here too
