perl - Performing a one-liner on multiple input files specified by extension -

i'm using following line split , process tab-delimited .txt file:

perl -lane 'next unless $. >30; @array = split /[:,\/]+/, $f[2]; print if $array[1]/$array[2] >0.5 && $array[4] >2' input.txt > output.txt 

is there way alter one-liner in order perform on multiple input files without specifying each individually?

ideally accomplished performing on files within current directory holding .txt (or other) file extension - , outputting set of modified files names e.g.:

input:

test1.txt test2.txt 

output:

test1mod.txt test2mod.txt 

i know can access filename modify $argv not know how go getting run on multiple files.

solution:

perl -i.mod -lane 'next unless $. >30; @array = split /[:,\/]+/, $f[2]; print if $array[1]/$array[2] >0.5 && $array[4] >2; close argv if eof;' *.txt 

$. needs reset otherwise throws division 0 error.

if don't mind different output file name,

perl -i.mod -lane'   next unless $. >30;   @array = split /[:,\/]+/, $f[2];   print if $array[1]/$array[2] >0.5 && $array[4] >2;   close argv if eof;  # reset $. each file. ' *.txt
