My goal is to find a Linux command sequence, which deletes some files if a special condition is fulfilled:
All files with the extensions
.cut.bak in the current directory shall be removed, IF there is no file having the same name, but extension
.mpg in the current directory.
Background: I am developing a tool for a Linux-based PVR, that allows cutting of recorded programs. For each recording (extension
.mpg) the segment markers are stored in a
.cut-file with the same name. When some recording gets moved/renamed/deleted, then the corresponding cut-file remains orphaned and shall be deleted. I already have implemented the removing of those useless cut-files in C. But I am wondering, whether there may be a (simple) system based solution. In this case it could be run via 'system' and & in the background, which would make my application more responsive...
I already asked a similar question for the recursive case (browsing also into subdirectories), here. There has been a (nearly) perfect answer by kos - but unfortunately it removes too many files, so it is not usable, and I was not able to figure it out... But the same idea can be used here, IF it is possible to parse and pipe the result of 'ls' linewise...
