Character: "?" is the Byte Order Mark (BOM) of the Unicode Standard. Specifically it is the hex bytes EF BB BF, which form the UTF-8 representation of the BOM, misinterpreted as ISO 8859/1 text instead of UTF-8. Show Sample Output

Use if you have pictures all over the place and you want to copy them to a central location Synopsis: Find jpg files translate all file names to lowercase backup existing, don't overwrite, preserve mode ownership and timestamps copy to a central location

Just shortened the awk a bit and removed sed. Edit: I'm assuming there are no spaces in the path. To support white space in pathname try: awk '($1 < 2048) {sub(/^[0-9]+[ \t]+/,""); print $0}'

Prints contents of current directory with the full path prepended to each entry. You can add '-type f' if you don't want the directories to show up (for those less familiar with find). I can't believe ls doesn't have an option for this. Show Sample Output

if you use disk-based swap then it can defeat the purpose of this function.

This is great for looking for files that have been updated recently. Logs especially or monitoring what files were added during an install.

This is best run as root to avoid permission denials that can produce false positives. Obviously you can specify a directory in the usual way: find -L dirname -type l I can't remember where I read about this or who deserves the credit for it. The find(1) manual page hints strongly toward it, however. Show Sample Output

tar does not have a -mtime option as find. tar appends all the file to an existing tar file.

Using `-exec cmd {} +` causes find to build the command using all matching filenames before execution, rather than once per file.

Note: the tar archive must not exist in order to create it. If exists it will only be updated and no already existent files in present search will still remain in the tar archive. The update option has to be used instead of create because the command tar may be executed more than once depending on the number of arguments that find throws. You can see maximum number of arguments with 'getconf ARG_MAX'

This sorts files in multiple directories by their modification date. Note that sorting is done at the end using "sort", instead of using the "-ltr" options to "ls". This ensures correct results when sorting a large number of files, in which case "find" will call "ls" multiple times.

This command is adapted from http://otomaton.wordpress.com/2012/12/26/find-broken-symbolic-links/ Solutions with find -L don't work when the link is a loop, an error message is printed.

su www-apache/ftp user and then check readable: find ~/ -type d \( -wholename '/dev/*' -o -wholename '/sys/*' -o -wholename '/proc/*' \) -prune -o -exec test -r {} \; -exec echo {} readable \; 2>/dev/null check writable: find ~/ -type d \( -wholename '/dev/*' -o -wholename '/sys/*' -o -wholename '/proc/*' \) -prune -o -exec test -w {} \; -exec echo {} writable \; 2>/dev/null

Convert some SVG files into PNG using ImageMagick's convert command. Run the conversions in parallel to save time. This is safer than robinro's forkbomb approach :-) xargs runs four processes at a time -P4

This will show all changes in all log files under /var/log/ that are regular files and don't end with `gz` nor with a number Show Sample Output

First, use find to find directories exactly one level below current directory, then create a tar file using the directory as the basename.

if you want to move with command mv large list of files than you would get following error /bin/mv: Argument list too long alternavite with exec: find /source/directory -mindepth 1 -maxdepth 1 -name '*' -exec mv {} /target/directory \; Show Sample Output
