[vti]

Hi all,


i want to delete lines where starts with "USER_PATH=/usr/ase..." and second line is "export USER_PATH."

Thanks for any help

Something like
/^USERPATH/,/export USER_PATH/ { next } # skip between lines
{ print } # print everything else

hi Salem
Thanks for help but i need to delete those lines and i also have to apply with a script cause i have lots of files which has same lines.

Put my previous program into a file, say
remlines

then write another script along the lines of this

for i *.txt; do  # for each txt file
  remlines $i > tmp$$  # remove the required lines
  cp tmp$$ $i          # copy the output back over the original
done
rm tmp$$               # tidy up

You'll want to omit the 'cp' command until you're confident that its all working properly
