`shell$ perl -pi.bak -le 's/(?<=[^n])n\|n(?=[^n])/^/ig' yourfile.txt` [download] will do the substitution and leave a backup file named yourfile.txt.bak UPDATE: it will not work, because your file has newlines (somehow I missed it). Try this instead: `perl -pi.bak -0377 -e 's/n([n\n]*)n/^$1^/ig' yourfile.txt` [download] []s, HTH, Massa	[reply] [d/l] [select]
