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,
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'
Is there a way to include both \r\n and \n in one regex to avoid the second substitute script (s/\n\(\)/\1/)? (4 Replies)

cut
CUT(1) General Commands Manual CUT(1)NAME
cut - select out columns of a file
SYNOPSIS
cut [ -b | -c] list [file...]
cut -f list [-d delim] [ -s]
OPTIONS -b Cut specified bytes
-c Select out specific characters
-d Change the column delimiter to delim
-f Select out specific fields that are separated by the
-i Runs of delimiters count as one
-s Suppres lines with no delimiter characters, when used
EXAMPLES
cut -f 2 file # Extract field 2
cut -c 1-2,5 file # Extract character columns 1, 2, and 5
cut -c 1-5,7- file # Extract all columns except 6
DESCRIPTION
[file...]" delimiter character ( see delim)" with the -f option. Lines with no delimiters are passwd through untouched"
Cut extracts one or more fields or columns from a file and writes them on standard output. If the -f flag is used, the fields are sepa-
rated by a delimiter character, normally a tab, but can be changed using the -d flag. If the -c flag is used, specific columns can be
specified. The list can be comma or BLANK separated. The -f and -c flags are mutually exclusive. Note: The POSIX1003.2 standard requires
the option -b to cut out specific bytes in a file. It is intended for systems with multi byte characters (e.g. kanji), since MINIX uses
only one byte characters, this option is equivalent to -c. For the same reason, the option -n has no effect and is not listed in this man-
ual page.
