I would like to do this:
replace the word "prod" with the word "special" but it may occur through the file naturally without a command, I only want it to happen when it has a specific command in front of it. The command will always look like this

Hi all,
I'm writing a script that replaces a value in a file. The file is formatted as follows:
So, for this example, I'd like to replace the value for param_two. The value for param_two can be a one, or two-digit number. It replaces the value in file.cfg, and directs the... (9 Replies)

Hi,
I tried to extract the time from `date` with sed.
(I know it works with `date +%H:%M:%S` as well)
I got three solutions of which just one worked. I thought "+" should repeat the previous expression 1 or more times and {n} should repeat the previous expression n times.

I am using the following sed script to remove new lines (\r\n and \n), except from lines starting with >:
sed -i ':a /^>/!N;s/\r\n\(\)/\1/;s/\n\(\)/\1/;ta'

bzfgrep
BZGREP(1) General Commands Manual BZGREP(1)NAME
bzgrep, bzfgrep, bzegrep - search possibly bzip2 compressed files for a regular expression
SYNOPSIS
bzgrep [ grep_options ] [ -e ] pattern filename...
bzegrep [ egrep_options ] [ -e ] pattern filename...
bzfgrep [ fgrep_options ] [ -e ] pattern filename...
DESCRIPTION
Bzgrep is used to invoke the grep on bzip2-compressed files. All options specified are passed directly to grep. If no file is specified,
then the standard input is decompressed if necessary and fed to grep. Otherwise the given files are uncompressed if necessary and fed to
grep.
If bzgrep is invoked as bzegrep or bzfgrep then egrep or fgrep is used instead of grep. If the GREP environment variable is set, bzgrep
uses it as the grep program to be invoked. For example:
for sh: GREP=fgrep bzgrep string files
for csh: (setenv GREP fgrep; bzgrep string files)
