We should note that, when we write shell scripts, we shouldn’t parse the output of ls. We can use the find command to pipe the filenames to awk as input: $ find. This can be used in place of the -nv options of rename and prename. There is no “dry-run” option for awk, however, if we remove the “ | sh“, awk will print all generated mv commands to stdout without executing them. We can pipe awk generated mv commands to the shell to do bulk renaming: awk '.' | sh Please bear in mind that the “.” after the find command denotes the current directory.Īwk is a powerful text-processing utility. In our case, all files with names containing “ backup” are targeted. The -exec argument tells find to execute rename for every matching file found. Log1-backup.xml log1.txt log2-backup.xml log2.txt log3.txt log4.txt Log1-backup.txt log1.txt log2-backup.txt log2.txt log3.txt log4.txt It looks for the first occurrence of txt in each filename, and replaces it with log.Īlternatively, we can use rename with the find command to target specific files: $ ls The rename command is pretty straightforward. log *.txtįile1.log file2.log file3.log file4.log file5.log Now, let’s use the rename command to rename our. This is because there is no “undo” or “restore” option for a bulk renaming operation. It is recommended to always do a dry-run to make sure that the changes are correct. The rename command with “ -nv” options shows the mistake clearly and gives us a chance to correct the command. Do note that it only supports one directory per renaming operation, though it can recurse through child folders within the selected directory.In this example, when we typed the command line, we had an extra dot in front of the replacement “ log” by mistake. This is where you select the directory that contains the files you want to batch rename. Once you run the app, it will be the first "Picker" tab. It provides a deb file for Debian-based distro and RPM package for Fedora, Mandriva and SUSE. To get started, go to its website and download the installer file for your distro. It is available for both Windows and Linux. For those who prefer a GUI tool for carrying out renaming operations, Métamorphose is quite a powerful tool to use. Métamorphose is a cross-platform file and folder mass renamer. Thanks to the -n option, the users will never have to put their files at risk (or their nerves at stake) since it offers a safe and useful preview of what the renamed files will look like.Īlso read: How to Fix the "No Space Left on Device" Error on Linux Métamorphose2 Using the rename command boils down to mixing a few basic patterns to achieve the desired result. To do it in the reverse, just switch the "oldname" and "newname" parts of the regular expression. In Debian-based Linux, type this in your terminal: If you are unable to use it in yours, you will have to install it. In many distributions of Linux, the rename command may not be available by default. That may sound scary, but don't give up on rename just yet - it can be used for plain batch renaming simply by following tutorials like this one. This command to rename files in Linux is slightly more advanced than mv because it requires the knowledge of, or at least a basic familiarity with, regular expressions. Options are written after mv but before the filenames. There's also the -v (verbose) option, which lists all changes that have been made by mv. An extra layer of protection is provided by the -i (interactive) option, which asks the user to confirm the file rename before it's actually applied. In the case of system files and folders, the user needs to obtain root permissions to rename files by prepending mv with sudo. Note that the mv command requires write permission for the folder containing the files.
