Re^2: extract (a range of) numbered lines from a file -- smarter oneliner 22chars

Nice!

perl -e "print +(0,<ARGV>)[eval pop]" linenumber.txt 1,3..5
[download]

You can omit the ARGV, and the blank after print, too:

perl -e "print+(0,<>)[eval pop]" linenumber.txt 1,3..5
[download]

22 :-)

perl -le'print map{pack c,($-++?1:13)+ord}split//,ESEL'

Re^3: extract (a range of) numbered lines from a file -- let's say 20 char oneliner by Discipulus (Canon) on Sep 21, 2016 at 20:27 UTC
Let's say 20.. `perl -E "say+(0,<>)[eval pop]" linenumber.txt 1,3..5` [download] I was sure to have tested the empty diamond, but evidently not.. ;=) L* PS 19 chars if I can cheat: `perl -snlE "say if $.~~[eval$R]" -- -R="2,3..5" linenumber.txt` [download] L* There are no rules, there are no thumbs.. Reinvent the wheel, then learn The Wheel; may be one day you reinvent one of THE WHEELS.	[reply] [d/l] [select]
