See the sample outputs: # find -iname findme ! -path. Similar way we can exclude multiple directories also. See the example: # find -iname findme|grep -v bit It does the find first then exclude the specific string. So there is no advantage considering the find command execution time. It do the grep after performing the find operation. We can ignore the location by using inverse grep “grep -v” option. If you are interested to read some Kubernetes topics you can check this page Method 3 : Simple 🙂 See the example pasted below: # find -iname findme ! -path. This is not much complicated compared to first method. egrep using -v flag with pipe between tokens surrounded by parens: egrep -v ' (defjkl)' filename.txt. grep command using -E flag with a pipe between tokens in a string: grep -Ev 'defjkl' filename.txt. One way to exclude the grep line from ps output is to use an additional grep with the -v option to invert the search: ps grep vi grep -v grep. Filtering out multiple lines with grep: Put these lines in filename.txt to test: abc def ghi jkl. The directory “bit” will be excluded from the find search! Method 2 : Using “! -path” Let’s now take a look at a couple of ways to remove the grep from our results. We can exclude directories by using the help of “ path“, “ prune“, “ o” and “ print” switches with find command. cry/findme Method 1 : Using the option “-prune -o” Lets see the output: # find -iname findme
To explain this, I created the following directories and files: There are different ways to exclude a directory or multiple directories in FIND command. Quick view on “ Find command and switches“

The result will be faster as compared to the full search. If the server has a lot of directories and we are sure about that the file / directory that we are searching is not in some directories, we can directly exclude those to improve the performance. In some cases, we have to exclude some directories from our search pattern to improve the search speed or efficiency. Here we go for excluding some directories from our find job. I have already listed different switches and its usages with examples. Yep, the command FIND has wide range of options to search what you actually looking for.

Is it possible to exclude a directory with find command? Exclude directories while doing running find command? I have a lot directories and how to exclude selected directories while performing the find command to save the find execution time. This exclude will help you to reduce the execution time while doing the find command. If you have a lot directories, it takes time to do the find operation.
In this blog article we are discussing how we can exclude some directories while doing the find command. We can use the find command to find files and directories based on different things like based on file permission, ownership, size, access time etc. Otherwise it is either let "as it" or completely removed - depending on nullglob.As a Linux server administrator or DevOps engineer we need to use find command quite frequently to find a lot of stuff from the server. In the unlikely event you have a file matching this pattern it would have been replaced. Here grep will try to list all the occurrences of wantedpattern in all the files from within currently directory and pass it to second grep to filter out the.
Here the pattern is -include=*.cmd (at whole since there is no space in there). Given a string, we can then test if the string belongs to this class of. But if there is no matching files, it either let the pattern as it (if nullglob is not set) or replace it with "nothing" (if nullglob is set). A regular expression(regex) is defined as a pattern that defines a class of strings. When the shell encounters a glob pattern (i.e.: containing * or ? or a few more special characters), it expands it with the matching files. So the result is: # nullglob is setĪn now, for the explanation. That is, I will recursively ( -r) search for the string skim starting with f.cmd, g.sh and sub but excluding any file matching the pattern '*.cmd'.īUT if in your environment the option nullglob is set, the same command expands to: grep ckim f.cmd g.sh sub -r On my system (where nullglob is unset), the following command: grep -exclude.cmd ckim -r Is expanded ('understood') by the shell as: grep -exclude.cmd ckim f.cmd g.sh sub -r That is, I will recursively (-r) search for the string skim starting with f.cmd, g.sh and sub but excluding any file matching the pattern '.cmd'. Is expanded ("understood") by the shell as: grep -exclude=*.cmd ckim f.cmd g.sh sub -r On my system (where nullglob is unset), the following command: grep -exclude=*.cmd ckim * -r So, given the following environment: sh$ touch f.cmd g.sh
There is a shell option called nullglob that controls the expansion of shell patterns when there is no matching file. So it seems the exclude option is not working for me. I see lots of grepped lines from *.cmd files.
