Find
find(1) is a file finder.
Installation
find(1) will be pre-installed on any Linux or BSD operating system, as a POSIX utility.
Usage
find(1) identifies files and, by default, simply prints them.
find(1) can alternatively execute a command on the file name. Note that this occurs in a subshell, so functions and environment variables are not accessible to the command.
find . --exec mv ../backup/{} \;
File Name
To find all files with a name matching a pattern, try:
find . -name '*.pyc' -exec rm {} \;
File Ownership
To find all files owned by user foo, try:
find . -user foo -exec chown bar {} \;To find all files in the group foo, try:
find . -group foo -exec chgrp bar {} \;
File Permissions
To find all files with some permission level, try:
find . -type d -perm 755
Conversely, to find all files with any other permission level, try:
find . -type f -not -perm 644 -exec chmod 644 {} \;
