General :: Find All Files Starting With A String Lsnr* Under Root Directory

Oct 31, 2010

I am looking for Windows Search equivalent looking for file name patterns (not file contents but file names)....

I am aware of "globbing" and wildcard recursive search functionality in ls but I am still not capable of finding files under directories.

for example: I want to find all files starting with a string lsnr* under root directory / and any sub-directories.....

ie I want to look for files like lsnr*.* anywhere under / and any sub-directories under / such as /dir1/dir2/dir4 and dir1/other/dir/someotherdir/sub-dir etc.

so if I have /dir1/lsnrcontrol and also have /dir1/dir/2/dir3/lsnr-tinit.dat then I want to list the files names etc.

how to do this using ls -R and wildcards.

General :: String Replace In Filenames - Files Already Contain The String "Soundtrack"

Jun 11, 2011

Moving right along, I have a folder of MP3 files containing various Movie sound tracks and scores. I'm using Audio Tag Tool to tag all the files at once with an "Artist" of "Soundtrack", and to inherit the "Title" tag from the file name. After that, I will rename all the files (Using Audio Tag Tool -- awesome program, btw) with the format "<Artist> - <Title>.mp3"

The problem, is many of my files already contain the string "Soundtrack", which would be redundant. I happen to be a perfectionist, so I'm unable to ignore it and move on. Hence my question to you fine folk: I want to delete all instances of "soundtrack" (-i case irrelevant) in the filenames before I go through the above steps. But, its not quite that simple. This is a sample of some of the file names:
