cut -d'/' -z -f 1 : print the 1st ( -f 1) /-separated ( -d /) field of null-delimited ( -z) data.head -z -n 5 : keep the first 5 ( -n 5) null-separated ( -z) lines.sort -rz -k 2 : this will take NULL-separated input ( -z) and sort it in reverse order ( -r) based on the value in the second /-separated ( -t'/') field of each line ( -k 2). ![]() stat -printf '%n/%Y\0' * : this will print out the name ( %n) of every file or directory in the current directory followed by a slash ( / I am using a slash since that is not allowed in a file name so can safely be used as a separator) and the file's modification time in seconds since the epoch ( %Y) and finally a NULL character ( \0).A safe way to do this would be: stat -printf '%n/%Y\0' * | sort -rz -t'/' -k 2 | head -z -n 3 |Ĭut -d'/' -z -f 1 | xargs -0 perl-rename 's/ /_/g' Since you want to replace spaces with _, your suggested approach will fail. We will need to type the following: mv file1.txt file2.txt As simple as that. It will break if your file names have any type of weirdness (spaces, newlines, control characters etc). Rename File on Linux Using the mv Command If we want to rename a file, we can do it like this: mv oldnamefile1 newnamefile1 Assuming we are located in the directory, and there is a file called file1.txt, and we want to change the name to file2.txt. And as obvious, several commands are available that allow a user to mass rename files on a Linux machine. Feel free to comment or edit this if you know how to do this, and want to replace the ls answer with this bottom part.Īs already pointed out, parsing ls is fragile. The Linux operating system depends primarily on packages and commands. If were a valid argument, this command chain would tell find to output files in the current directory separated with a NUL character, and then sort, head, and xargs would all accept this as the deliminator rather than a newline - making the whole process much more consistent. That method looks something like this: GNOME tip Using GNOME, you can go to Settings -> Details to view and change the static and pretty hostnames. Hi, I have a shell script that is run by user x on daily basis, which attempts to rename one file that is created by user y and user y have changed the mode. Open file descriptors for oldpathare also unaffected. Any other hard links to the file (as created using link(2)) are unaffected. mindepth 1 -maxdepth 1 -print0 | sort -Z | head -z -n5 | xargs -0 rename 's/ /_/g' This command allows you to change the kernel parameter for your transient name without having to reboot the system. rename() renames a file, moving it between directories if required. If someone else knows how to do this, you'd probably end up with something like: find. However, I don't know how to sort by last modification date with find. This breaks for file names which contain the newline character using a command that's meant for parsing like find would be much better. It offers more features than the mv command but can be more challenging to use since it requires basic knowledge of Perl expressions. This should work - but parsing ls is fragile. The rename command is used to rename multiple files or directories in Linux. xargs will take in a number of newline-separated arguments, and pass them all to a single rename command. This uses your original command almost exactly, but with xargs to do the final completion. For this, you can use pipes and the xargs command to execute the final rename. Renaming files and directories is simply a case of moving a file or a directory from one name to. The mv command can be used on files in the same directory, or with files in other locations. With that said, the simplest solution does seem to be using ls (as find does not offer a sort-by-modification-date option). mv command is used to rename files and directories. In this article, we’ll refer to it as rename. Since the util-linux package is a standard package distributed by, the rename command is available in all Linux distributions by default. It replaces only the first occurrence of some text in a filename. Its output is meant for human consumption, and this solution will fail for some legitimate file names (like those which contain newline characters, for example) The rename Command The rename command is from the util-linux package.
