Terminal - Commands using find - 1,070 results
find . -exec chmod o+rx {}\;
find . -exec grep -Hn what \{\} \; | less
2014-02-17 09:59:01
User: ynedelchev
Functions: find grep what

This command will traverse all of the folders and subfolders under current working directory. For every file inside it, it will do a search inside the content of the file for a specific term 'what'. Then it will print a list of the lines that contain that term (and match that pattern). Each matching line will be preceded with the path and name to the file and then the line number iside taht file wehre the pattern was found. Then the actual content of the matching lien will be printed.

The output will be piped throug less, so that the user can scroll through it if it goes beyond the limits of the current display window.

find . -name *.properties -exec /bin/echo {} \; -exec cat {} \; | grep -E 'listen|properties'
find . \( -not -path "./boost*" \) -type f \( -name "*.jpg" -or -name "*.png" -or -name "*.jpeg" \) 2>/dev/null

If you need to find some pictures on your disk but excluding some path.

find /logdir -type f -mtime +7 -print0 | xargs -0 -n 1 nice -n 20 bzip2 -9
find $1 -not -iwholename "*.svn*" -type f | xargs md5sum | awk '{print $2 "\t" $1}'

User: dronamk
Functions: awk find md5sum xargs

recurse through all files, get the message hash, flip the output as filename, hash value

find . -mtime +30 -exec mv {} old/ \;

User: minnmass
Functions: find mv
Tags: bash file

Use find's built-in "exec" option to avoid having to do any weirdness with quoting.

find * -regextype posix-extended -regex '.*\.(ext_1|ext_2)' -exec cp {} copy_target_directory \;
for i in $(find . -mtime +30); do mv $i old/; done
2014-02-05 01:24:45
User: valferon
Functions: find mv
Tags: bash file

Will move in that case every file in the current folder older than 30 days to the "old" folder

Replace "mv $i old/" by any command such as rm / echo to do something different.

find /path/to/somewhere -newermt "Jan 1"

This command uses -newerXY to show you the files that are modified since a specific date. I recommend looking for "-newerXY" on the manpage to get the specifics.

find . -name "*.URL" | while read file ; do cat "$file" | sed 's/InternetShortcut/Desktop Entry/' | sed '/^\(URL\|\[\)/!d' > "$file".desktop && echo "Type=Link" >> "$file".desktop ; done
find . -type f -regex ".*/core.[0-9][0-9][0-9][0-9]$"

User: H3liUS
Functions: find

Will find and list all core files from the current directory on. You can pass | xargs rm -i to be prompted for the removal if you'd like to double check before removal.

find . -name '*.sh' -exec bash -n {} \;
2014-01-17 16:20:36
User: tsener
Functions: bash find

Check all bash scripts in current dir for syntax errors WITHOUT running them.

find . -name "pattern" -type f -exec du -ch {} + | tail -n1
echo $(($(find . -name "pattern" -type f -printf "+%s")))

User: flatcap
Functions: echo find

Use find's internal stat to get the file size then let the shell add up the numbers.

find . -name "pattern" -type f -printf "%s\n" | awk '{total += $1} END {print total}'

User: pdxdoughnut
Functions: awk find

Using find's internal stat to get the file size is about 50 times faster than using -exec stat.

find . -name "pattern" -exec stat -c%s {} \; | awk '{total += $1} END {print total}'

User: Koobiac
Functions: awk find stat

Find files and calculate size with stat of result in shell

find ./ -name '*:*' -exec rename 's/:/_/g' {} +
for i in */; do echo $(find $i -type f -regextype posix-extended -regex ".*\.(mp3|ogg|wav|flac)" | wc -l) $i ; done
find . -type d -maxdepth 1 -print0 | xargs -0 -I{} sh -c 'find "{}" -type f | grep "ogg\|mp3\|wav\|flac$" | wc -l | tr -d "\n"; echo " {}"'
2013-12-22 13:40:29
User: dbrgn
Functions: echo find grep sh tr wc xargs

This lists the number of ogg/mp3/wav/flac files in each subdirectory of the current directory. The output can be sorted by piping it into "sort -n".

find . -iname "*.mp3" | mpg123 -Z --list -
find */*.c | xargs grep 'mcs'
find -regextype posix-egrep -regex '.*\.(css|js)$' | xargs -I{} sh -c "echo '{}' && yuicompressor '{}' | gzip -c > '{}.gz'"
find /path/to/dir -type f -exec cachedel '{}' \;

This is just another example of what the nocache package is useful for, which I described in http://www.commandlinefu.com/commands/view/12357/ and that provides the commands

nocache <command to run with page cache disabled>

cachedel <single file to remove from page cache>

cachstats <single file> # to get the current cache state

Often, we do not want to disable caching, because several file reads are involved in a command and operations would be slowed down a lot, due to massive disk seeks. But after our operations, the file sits in the cache needlessly, if we know we're very likely never touching it again.

cachedel helps to reduce cache pollution, i.e. frequently required files relevant for desktop interaction (libs/configs/etc.) would be removed from RAM.

So we can run cachedel after each data intensive job. Today I run commands like these:

<compile job> && find . -type f -exec cachedel '{}' \; &> /dev/null # no need to keep all source code and tmp files in memory

sudo apt-get dist-upgrade && find /var/cache/apt/archives/ -type f -exec cachedel '{}' \; # Debian/*buntu system upgrade

dropbox status | grep -Fi idle && find ~/Dropbox -type f -exec cachedel '{}' \; &> /dev/null # if Dropbox is idle, remove sync'ed files from cache
