Re: Keep only X number of entries of a file using a delimeter

I imagine your input looks like this:

#
Entry 1
...
#
Entry 2
...
[download]

You can use $/ aka the Input record separator:

perl -pe 'BEGIN { $/ = "#" } exit if $. > 500' input-file
[download]

$. contains the record number.

Hi, interesting approach! Could you please re-write this to a "normal" script (i.e. not one-liner)?	[reply]

Sure. Just add `-MO=Deparse` [download] before the switches. لսႽ† ᥲᥒ⚪⟊Ⴙᘓᖇ Ꮅᘓᖇ⎱ Ⴙᥲ𝇋ƙᘓᖇ	[reply] [d/l]
