![]() To save the value permanently, as the linked post mentions at the end, you'll need to add the export GREP_COLORS=. The quotes ensure that the shell passes BML\.I to grep. It has two counterparts EGREP and FGREP which. Note there are two levels of escaping in the above. The natural alterative to the Windows FIND/FINDSTR combination is the UNIX equivalent GREP. Meaning for each parameter: -n Show relative line number in the file 'yourString' String for search, followed by a wildcard character -r Recursively search subdirectories listed. (period) since by default it matches against any character, and specify -w to match a specific word e.g. The Emacs command colors the output and makes found lines clickable: When you click a search hit, Emacs visits the target file at the occurrence. You can filter the results by minimum and/or maximum filesize (4), by file type (5) and by location (6). The dot at the end searches the current directory. The Emacs ‘grep’ command lets you run the Unix or GNU/Linux ‘grep’ program, which searches files for lines that match a regular expression (regexp). All matches in the file are highlighted in yellow. Once the shell exits, however, the exported value is not saved. 14 Answers Sorted by: 1105 grep -nr 'yourString'. If you don't export the value, then it is local to your shell only, and grep will not see it, even when launched from Bash. Since grep is a subprocess, it needs the variable to be exported in order to get the updated value. Use the backslash before pipe for regular expressions. The patterns need to be enclosed using single quotes and separated by the pipe symbol. exporting a variable in the shell (Bash, most likely, in your case) means that any subprocess that you launch from that shell instance will receive the exported value. The basic grep syntax when searching multiple patterns in a file includes using the grep command followed by strings and the name of the file or its path. The locale for category LCfoo is specified by examining the three environment variables LCALL, LCfoo, and LANG, in that order. Without exporting, I prefer those things not to be saved yet The behavior of grep is affected by several environment variables, the most important of which control the locale, which specifies how grep interprets characters in its patterns and data. Per the color-charts mentioned in the Ask Ubuntu post that linked in the comments.įor instance: export GREP_COLORS='ms=01 31:mc=01 31:sl=:cx=:fn=31:ln=32:bn=32:se=36' To change the filename color, modify the fn value in the following line: export GREP_COLORS='ms=01 31:mc=01 31:sl=:cx=:fn=35:ln=32:bn=32:se=36'
