Awk or grep question -


i have datafile

[abc] def ghi [jkl] [mno]

from file; can run grep , lines have "[" in them. how can contents of text inside "[]".

for example:

abc jkl mno

thanks

sed -n 's/\[\(.*\)\]/\1/p' file

explanation: -n suppresses printing of each line stdout, /p @ end of regex re-enables behavior causing matching lines printed. regex matches between brackets , replaces entire line it.
