| # List of cheatsheet for linux find. | |
| # Taken from here http://alvinalexander.com/unix/edu/examples/find.shtml | |
| # basic 'find file' commands | |
| # -------------------------- | |
| find / -name foo.txt -type f -print # full command | |
| find / -name foo.txt -type f # -print isn't necessary | |
| find / -name foo.txt # don't have to specify "type==file" | |
| find . -name foo.txt # search under the current dir | |
| find . -name "foo.*" # wildcard | |
| find . -name "*.txt" # wildcard | |
| find /users/al -name Cookbook -type d # search '/users/al' | |
| # search multiple dirs | |
| # -------------------- | |
| find /opt /usr /var -name foo.scala -type f # search multiple dirs | |
| # case-insensitive searching | |
| # -------------------------- | |
| find . -iname foo # find foo, Foo, FOo, FOO, etc. | |
| find . -iname foo -type d # same thing, but only dirs | |
| find . -iname foo -type f # same thing, but only files | |
| # find files with different extensions | |
| # ------------------------------------ | |
| find . -type f \( -name "*.c" -o -name "*.sh" \) # *.c and *.sh files | |
| find . -type f \( -name "*cache" -o -name "*xml" -o -name "*html" \) # three patterns | |
| # find files that don't match a pattern (-not) | |
| # -------------------------------------------- | |
| find . -type f -not -name "*.html" # find all files not ending in ".html" | |
| # find files by text in the file (find + grep) | |
| # -------------------------------------------- | |
| find . -type f -name "*.java" -exec grep -l StringBuffer {} \; # find StringBuffer in all *.java files | |
| find . -type f -name "*.java" -exec grep -il string {} \; # ignore case with -i option | |
| find . -type f -name "*.gz" -exec zgrep 'GET /foo' {} \; # search for a string in gzip'd files | |
| # 5 lines before, 10 lines after grep matches | |
| # ------------------------------------------- | |
| find . -type f -name "*.scala" -exec grep -B5 -A10 'null' {} \; | |
| # (see http://alvinalexander.com/linux-unix/find-grep-print-lines-before-after-search-term) | |
| # find files and act on them (find + exec) | |
| # ---------------------------------------- | |
| find /usr/local -name "*.html" -type f -exec chmod 644 {} \; # change html files to mode 644 | |
| find htdocs cgi-bin -name "*.cgi" -type f -exec chmod 755 {} \; # change cgi files to mode 755 | |
| find . -name "*.pl" -exec ls -ld {} \; # run ls command on files found | |
| # find and copy | |
| # ------------- | |
| find . -type f -name "*.mp3" -exec cp {} /tmp/MusicFiles \; # cp *.mp3 files to /tmp/MusicFiles | |
| # copy one file to many dirs | |
| # -------------------------- | |
| find dir1 dir2 dir3 dir4 -type d -exec cp header.shtml {} \; # copy the file header.shtml to those dirs | |
| # find and delete | |
| # --------------- | |
| find . -type f -name "Foo*" -exec rm {} \; # remove all "Foo*" files under current dir | |
| find . -type d -name CVS -exec rm -r {} \; # remove all subdirectories named "CVS" under current dir | |
| # find files by modification time | |
| # ------------------------------- | |
| find . -mtime 1 # 24 hours | |
| find . -mtime -7 # last 7 days | |
| find . -mtime -7 -type f # just files | |
| find . -mtime -7 -type d # just dirs | |
| # find files by modification time using a temp file | |
| # ------------------------------------------------- | |
| touch 09301330 poop # 1) create a temp file with a specific timestamp | |
| find . -mnewer poop # 2) returns a list of new files | |
| rm poop # 3) rm the temp file | |
| # find with time: this works on mac os x | |
| # -------------------------------------- | |
| find / -newerct '1 minute ago' -print | |
| # find and tar | |
| # ------------ | |
| find . -type f -name "*.java" | xargs tar cvf myfile.tar | |
| find . -type f -name "*.java" | xargs tar rvf myfile.tar | |
| # (see http://alvinalexander.com/blog/post/linux-unix/using-find-xargs-tar-create-huge-archive-cygwin-linux-unix for more information) | |
| # find, tar, and xargs | |
| -------------------- | |
| find . -name -type f '*.mp3' -mtime -180 -print0 | xargs -0 tar rvf music.tar | |
| (-print0 helps handle spaces in filenames) | |
| # (see http://alvinalexander.com/mac-os-x/mac-backup-filename-directories-spaces-find-tar-xargs) | |
| # find and pax (instead of xargs and tar) | |
| # --------------------------------------- | |
| find . -type f -name "*html" | xargs tar cvf jw-htmlfiles.tar - | |
| find . -type f -name "*html" | pax -w -f jw-htmlfiles.tar | |
| # (see http://alvinalexander.com/blog/post/linux-unix/using-pax-instead-of-tar) | |
| # exclude files from other devices (like depreceted -xdev in macOS). For linux: -xdev | |
| find -x . -type f -name "*.java" |
One very useful thing that could have a place here is
-xdevwhich prevents find from indexing other filesystems that might me in the path.This is particularly useful when a autofs or any other kind of remote mount is located within the search path.
Searching remote servers is usually not desired since it is very slow.
Just my idea
👍
Hi, can you point me to any relevant documentation about the -xdev being deprecated?
My current find version (under Fedora 32) doesn't accept a -x toggle..

I am using macOS, and it says that -x is equivalent to the deprecated -xdev primary. here . There could be difference between macOS and Linux.
