find . type f in unix
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' dir
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 https://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 https://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 https://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 https://alvinalexander.com/blog/post/linux-unix/using-pax-instead-of-tar)
