  • Thanks. So you want to sort only on filenames and not on the whole path? Whole path is easier. Do the paths contain spaces? Is something like wp-admin/foo bar.php possible?

  • The reason of the sorting is so that I can then compare the file2.txt with a file3.txt for non-matching lines for "file change detection". I figure this is more efficient with alphabetical sorting. It's better to have space tolerable code just in case.

If your aim is to sort a text file based on specific columns you don't need to change the column order if you use the -k option of GNU sort. To only sort based on the 2nd and subsequent (white-space delimited) columns use:



sort -k 2


Additionally I advise you to use the C or POSIX collation locale to compare and sort path names or you may receive unexpected results due to case-insensitivity or special characters:



LC_COLLATE=POSIX sort ...

How about:



awk ' print $2, $1 ' < file | sort > file2


This will take the data from the file called 'file', swap the two fields and sort them into file 'file2'

I do not come from a particularly wealthy family, (very low middle class), and was only able to afford my education via school loans/scholarships and working low-wage jobs, with no support from my family or anyone else.
