The sed utility is a stream editor that reads one or more
text files, makes editing changes according to a
script of
editing commands, and writes the results to standard
output.
The script is obtained from either the script
operand
string, or a combination of the option-arguments from
the -e
script and -f script_file options.
The sed utility is a text editor. It cannot edit
binary
files or files containing ASCII NUL (\0) characters
or very
long lines.
