perl - Quickest/most concise bash one-liner for extracting specified lines from a file -


i want extract lines specific line numbers file (i have 20-50 line numbers, file has 30,000 lines). far, concise way i've found e.g.:

gawk 'begin {split("13193,15791,16891", a, ",")} nr in a' <file_name> 

but seems should able further reduce amount of typing involved. i've looked @ sed think need -n , -p each line number, thought cat -n grep it's more verbose above. know better way?

sed can more concise:

sed -n "13193p;15791p;16891p" file_name
