Sed Notes

Published on 29 July, 2020 by Amanda
Replace text in file
sed -i '/pattern to match/new string' ./infile Delete lines in a file(s)
In this example lines containing -- are deleted.
sed -i '/--.*/d' ./* sed -i -e '/^\s*#\([^!]\|$\)/d'
Where:
^ = start of line
\s* = zero or more whitespace characters
# = one hash mark
\([^!]\|$\) = followed by a character which is not ! or end of line.
