Answer / varakumar

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.

Answer / bhaskar

Usage: sed [OPTION]... {script-only-if-no-other-script}
[input-file]...

-n, --quiet, --silent
suppress automatic printing of pattern space
-e script, --expression=script
add the script to the commands to be executed
-f script-file, --file=script-file
add the contents of script-file to the
commands to be executed
-i[SUFFIX], --in-place[=SUFFIX]
edit files in place (makes backup if
extension supplied)
-c, --copy
use copy instead of rename when shuffling
files in -i mode
(avoids change of input file ownership)
-l N, --line-length=N
specify the desired line-wrap length for
the `l' command
--posix
disable all GNU extensions.
-r, --regexp-extended
use extended regular expressions in the script.
-s, --separate
consider files as separate rather than as a
single continuous
long stream.
-u, --unbuffered
load minimal amounts of data from the input
files and flush
the output buffers more often
--help display this help and exit
--version output version information and exit

If no -e, --expression, -f, or --file option is given, then
the first
non-option argument is taken as the sed script to interpret.
All
remaining arguments are names of input files; if no input
files are
specified, then the standard input is read.
