用于删除特定文件的 Shell 脚本

Question

I have a multiple layers of folder example a(b(c(d(u,v))))

Here in every level there is a folder sync , for example in every directory sync folder is present ie a/sync , a/b/sync and so on.

I am looking to write a shell or tcl script which will go in every folder and delete the particular file(sync).

Can anyone guide me?
Thanks
Good day

Answer 1

You can use rmdir ./**/.sync .
This will search recursive in the current directory for every directory called sync and delete it.

For use of the double asterisk also see this answer

Note that this will only delete directories(folders) and if it's not empty.

To remove the directories with all files in it, use rm -r ./**/.sync

Answer 2

Find and remove...

find . -type d -name sync -exec rm -rf {} \;

Explanations:

• . : search for current directory
• -type d : search for directories only
• -name sync : search for file/directory named " sync "
• -exec ... : execute this command on each file/directory found
  • rm -rf : remove file and directories named ...
  • {} : is replaced by each file/directory found by find command
  • \; : and of -exec option

Answer 3

Since all the answers so far have been shell approaches, here's a tcl one:

#!/usr/bin/env tclsh

proc delete_syncs {dir} {
    foreach subdir [glob -directory $dir -types d -nocomplain *] {
        delete_syncs $subdir
        set sync [file join $subdir .sync] ;# Or sync or .SYNC or whatever it's actually named
        if {[file exists $sync]} {
            file delete -force -- $sync
        }
    }
}
foreach basedir $argv {
    delete_syncs $basedir
}

Takes the base directory (Or directories) to scan as command line arguments.
