(Bash) Howto Convert Filenames to All Lowercase - jonhenshaw

Sun, 27 Jul 2008 17:34:08 GMT

Line 6 starts a loop (which ends with line 15). The ls command returns a list of filenames which are sequentially assigned to the shell variable x. The if test (lines 8 through 10) checks to see if the current filename is that of a plain file. If not, the remainder of the statements in the current loop iteration are skipped. If line 11 is to be executed we know that we have an ordinary file. Using tr we convert the filename to lowercase and assign the new name to the shell variable lc. Line 12 then checks to see if the lowercase version of the name differs from the original. If it does, line 13 is executed to change the name of the original file to the new lowercase name. The -i option causes the mv to prompt for confirmation if executing the command would overwrite an existing filename. __________________________

This code is POC only -- actually using it would violate Google's TOS, which forbids scraping. It is published here for educational value only.

The results will be prepended with digits, followed by a dot and some whitespace (Lynx adds these).
