Delete lines from a file 1

[panpol]

Hi,
I have a file with 2 numbers, for example:

215
816

Can I use the numbers of this file, to delete some lines of one other file with the use of sed,awk,…?Is there a way to pass this numbers as parameters to sed or awk and delete the lines from 215 to 816 of one other file?

Thanks

Hi

Like this ?

awk 'BEGIN{getline f;getline t}FNR==f,FNR==t{next}1' linenumbers.txt inputfile > outputfile

A pure legacy unix way (;-)) :
sed "`paste -sd, /path/to/numbers`d" /path/to/otherfile

Hope This Helps, PH.

[futurelet]

NR < 3 { limits[NR] = $0 ; next }
FNR==limits[1], FNR==limits[2] { next }
8

[tt]awk -f skiplines.awk limits.txt infile >outfile[/tt]
