I must go through some files to change a certain string within text files to another string. I use openSUSE and folders are mounted by cifs.
Text to be replaced (only in .m extension) is U:\FOLDER and new string is N:
That works fine with spaces in directory names etc., but this process changes every .m file's timestamp to current. We could use those previous timestamps. That search string is included in about 5 % of those .files, so it usually doesn't change the file at all. I think I could search that file before using sed that way, but it would be slower and I have to search a lot of files.
I have a log file on our system which fills up with lines that have been timestamped, as follows....

Okay so here's something that's confusing me: I have a script that's designed to remove the words "new_" from the front of any file except two exceptions and it looks something like this...

fgrep
fgrep(1) User Commands fgrep(1)NAME
fgrep - search a file for a fixed-character string
SYNOPSIS
/usr/bin/fgrep [-bchilnsvx] [-e pattern_list] [-f pattern-file] [pattern] [file...]
/usr/xpg4/bin/fgrep [-bchilnsvx] [-e pattern_list] [-f pattern-file] [pattern] [file...]
DESCRIPTION
The fgrep (fast grep) utility searches files for a character string and prints all lines that contain that string. fgrep is different from
grep(1) and from egrep(1) because it searches for a string, instead of searching for a pattern that matches an expression. fgrep uses a
fast and compact algorithm.
The characters $, *, [, ^, |, (, ), and are interpreted literally by fgrep, that is, fgrep does not recognize full regular expressions as
does egrep. These characters have special meaning to the shell. Therefore, to be safe, enclose the entire string within single quotes (').
If no files are specified, fgrep assumes standard input. Normally, each line that is found is copied to the standard output. The file name
is printed before each line that is found if there is more than one input file.
OPTIONS
The following options are supported:
-b Precedes each line by the block number on which the line was found. This can be useful in locating block numbers by con-
text. The first block is 0.
-c Prints only a count of the lines that contain the pattern.
-e pattern_list Searches for a string in pattern-list. This is useful when the string begins with a -.
-f pattern-file Takes the list of patterns from pattern-file.
-h Suppresses printing of files when searching multiple files.
-i Ignores upper/lower case distinction during comparisons.
-l Prints the names of files with matching lines once, separated by new-lines. Does not repeat the names of files when the
pattern is found more than once.
-n Precedes each line by its line number in the file. The first line is 1.
-s Works silently, that is, displays nothing except error messages. This is useful for checking the error status.
-v Prints all lines except those that contain the pattern.
-x Prints only lines that are matched entirely.
OPERANDS
The following operands are supported:
file Specifies a path name of a file to be searched for the patterns. If no file operands are specified, the standard input will
be used.
/usr/bin/fgrep
pattern Specifies a pattern to be used during the search for input.
/usr/xpg4/bin/fgrep
pattern Specifies one or more patterns to be used during the search for input. This operand is treated as if it were specified as
-e pattern_list.
USAGE
See largefile(5) for the description of the behavior of fgrep when encountering files greater than or equal to 2 Gbyte ( 2**31 bytes).
ENVIRONMENT VARIABLES
See environ(5) for descriptions of the following environment variables that affect the execution of fgrep: LC_COLLATE, LC_CTYPE, LC_MES-
SAGES, and NLSPATH.
EXIT STATUS
The following exit values are returned:
0 If any matches are found
1 If no matches are found
2 For syntax errors or inaccessible files, even if matches were found.

Ideally, there should be only one grep command, but there is not a single algorithm that spans a wide enough range of space-time tradeoffs.
Lines are limited only by the size of the available virtual memory.
/usr/xpg4/bin/fgrep
The /usr/xpg4/bin/fgrep utility is identical to /usr/xpg4/bin/grep -F (see grep(1)). Portable applications should use /usr/xpg4/bin/grep
-F.
