#Bash find files by date portable

Touch -t $(date -d '10 MINUTE AGO' +%Y%m%d%H%M.%S) end_date type f -newermt ! -newermt įind files accessed in a range of timestamps (using files as timestamp), from 1 hour ago to 10 minutes ago: touch -t $(date -d '1 HOUR AGO' +%Y%m%d%H%M.%S) start_date mtime +n : File was modified more than nx24 hours agoįind files modified in a range of dates, from to : find. mtime -n : File was modified less than nx24 hours ago mtime n : File was modified nx24 hours ago Use -atime and -ctime for access time and status change time respectively. mtime -2įind files that have not been modified within the last 2 days find. mmin +n : File was modified more than n minutes agoįind files that have been modified within the last 2 days: find. mmin -n : File was modified less than n minutes ago mmin n : File was modified n minutes ago The above example are searching only on the modified time - to search on access times, or changed times, use a, or c accordingly. To find files that have not been modified within the last 2 hours: $ find. To find files that have been modified within the last 2 hours: $ find. On an ext filesystem, each file has a stored Access, Modification, and (Status) Change time associated with it - to view this information you can use stat myFile.txt using flags within find, we can search for files that were modified within a certain time range. Finding file by access / modification time The mysterious _ is necessary because the first argument to bash -c 'script' is used to populate $0. (The script will need to handle these names correctly, of course every variable which contains a file name needs to be in double quotes.)

This way, the -exec receives the file names in a form which is completely correct and portable the bash -c receives them as a number of arguments, which will be found in, correctly quoted etc. The preferred way to do this is to skip the xargs command and let find call the subprocess itself: find. This is a GNU extension, and may not work in other versions of find and xargs. In the above example, the -print0 and -0 flags specify that the file names will be separated using a null byte, and allows the use of special characters, like spaces, in the file names. If your files names or directories have a space character in them, this command may choke a solution is to use the following find. The -r option specifies to xargs to not run chmod if find did not find any files. (which is your current working directory), and execute chmod 770 on them. The above command will recursively find all directories ( -type d) relative to. Sometimes we will need to run commands against a lot of files. To find symlinks, use the -type l flag $ find. To find block devices, use the -type b flag $ find /dev -type b To find directories, use the -type d flag $ find.

To find files, use the -type f flag $ find. To search for directories only (not regular files), use -type d: find /opt -type d To search for files only (not directories), use -type f: find /opt -type f To find all files/directories located in a specific directory $ find /opt To find files/directories which name begin with abc and end with one alpha character following a one digit: $ find. To find files/directories matching one of many extensions, use the or flag: $ find. To find files/directories with a specific extension, use a wildcard: $ find.

To find files/directories with a specific name, relative to pwd: $ find. Searching for a file by name or extension
