So typing rm **/*.bar in globstar enabled bash will indeed recursively delete all matching files in subfolders. Typing echo **/*.bar will show a list of all files ending in. If you give this option and a file is deleted between the time find. In recent versions of bash, for example, you can turn on an option called globstar which will do recursive expansion. ignorereaddirrace Normally, find will emit an error message when it fails to stat a file.
There are some ways of controlling globbing. So when you type rm *.bar, what's actually happening is that the shell expands the argument list to foo.bar, then passes that to the rm command. So typing echo * in the same directory will output foo.bar. One of the most common expansions is *, which is expanded to filenames in the current directory.Ī simple way to look at globs at work is to use echo, which prints back all arguments passed to it through the shell. You can see a list of bash file name expansions here. One of these is called 'file name expansion', otherwise know as 'globbing'. What's happening here is that your shell, which is the program you are using to type in commands, is performing some transformations before passing the arguments on to the command. However if you type rm *.bar in the same directory, it will delete the file. In other words, this command performs a search for files in the current directory that have been modified at least 30 days ago and then prints the names of. Note the single quotes around the file pattern, they tell the shell to pass the argument to the shell as it is. So if you are in a directory containing the file foo.bar, typing delete 'foo.*' will result in rm: foo.*: No such file or directory. In the case of rm, they are interpreted as a list of fully qualified filenames to be deleted. ( shopt -s globstar dotglob stat -format 's n' - /.log sort -rn ) This: runs in a sub-shell, so that the shopt statements dont affect the current/running shell. Programs like this can be started from the command line and can read a list of arguments prog arg1 arg2 arg3 when they start up. This little program takes care of unlinking files. You can locate the binary by typing which rm. When you type a command like this, work is split up between the shell you are using (let's assume bash) and the command binary. Yes, rm *.xvg will only delete files ending with. Good day, I've found an easy way to find files that have certain content, but I would like to create a bash script to do it quickier, The script is: /bin/bash DIRECTORY(cd dirname.
