Can anyone explain this command to me?


A file is passed to this command and the output piped to a file.


perl -pe 's/\e&k[0-9]S\e&l[0-9]H\eE//'


What it seems to do is cut everything between the first / and the
second /, but can't quite get the sense of what is being cut.


Thanks for your help

They are PCL escape sequences used to control printer output.
Most likely the file was created by a "Print to File" command
within an application.
