Searching files for content not matching given string By default, grep search does not include searching in sub-directories.

You can search for all files in a given path or folder or directory, including sub-directories using grep -r. Searching files recursively or all files in a given directory If grepВ finds no matches, it gives no output. Put theВ grepВ command inside $()В and those filenames can be used on the command line.Дo note that if grepВ finds more than one match per file, it still only prints the name once. This can be quite useful for scripting as it allows us to use pipeline to output file names to do further processing. If you are not interested in output of all lines containing the matching pattern and are just interested in filenames, you can do so using grep -l: grep -l sum *.sh This option is particularly useful for finding words anywhere that you might have mixed-case text. One can perform case insensitive search through use of grep -i: grep -i sum break-point.sh However windows users are used to perform case-insensitive searches. Shell search using grep is case-sensitive, as its nature of underlying OS. *ДЄgain, the second argument can be a more complex regular expressions.В These regular expressions are not the same as the shellвЂ™s pattern matching, though they can look similar at times. Of course, the shell doesnвЂ™t care how much pathname you type, so we could have done something like this: grep sum. Not all the files through which you want to search may be that conveniently located. Ps4-variable.sh:sum=$(($one_val + $two_val))ДЄs you may have noticed, the filename of each matching file is printed first in the output, before the line containing the matching string.

If you want to search all files in a given directory, use the wildcard ( *): grep sum *.shД«reak-point.sh:sum=$(($one_val + $two_val)) For example, if you want to find a string literal_string with files ending in. This can be done by passing regular expressions for the filename. Search for given string in Multiple files

We could have given full path (in unix-like format) and it would happily process it: grep sum /mnt/d/mohit/src/bash/break-point.sh This file break-point.sh just happens to be present in our current directory. The output will matches all the lines containing the string literal_string from the file specified with each new match present on a new line: grep sum break-point.sh This can simply be obtained by grep literal_string filename.
