Hi all, I am trying to take an expression in shell that works for me and translate it into Perl however it is giving me fits! Basically I'm trying to grep out all instance of /usr, /platform, /sbin and /lib in a file and return all other lines to a file. This is the bit that strips out the exceptions: 

egrep -v '^/usr$|^/sbin$|^/platform$|^/lib$' <file name>

[download]

In Perl I have tried: 

grep /!^(\/usr|\/sbin|\/platform|\/lib)$/

[download]

This didn't do it. Tried many variations that ended in error. Any help on this would be greatly appreciated!
