If you do not quote the operand of -I, it is expanded by the shell before running the 'ls' command and only the first word produced by the expansion is used as the operand of -I. The remaining words produced by the expansion are seen by 'ls' as the list of files to be listed. You can consider using the -x option of bash to see the exact command being invoked. This is just how bash (as well as any other POSIX-compatible shell) works. Nothing to fix here... |
Created attachment 1312196 [details] Several commands with "ls -I" Description of problem: ls -I produces inconsistent outputs when the filter is not written with quotes Version-Release number of selected component (if applicable): 6.something How reproducible: Very easy to reproduce Steps to Reproduce: 1. Touch several files with several of them starting with the same pattern $ touch mybody $ touch thisisMY205 $ touch thisisMYTRALALA $ touch THERING $ … 2. Write down some "ls -I" commands with wildcards 3. Conclude that ls -I malfunctions when the filter for excluding files matches at least 2 files. Actual results: $ ls -I mybody* thisisMY205 thisisMYTRALALA THERING $ ls -I thisis* thisisMYTRALALA $ ls -I "thisis*" mybody THERING Expected results: $ ls -I thisis* mybody THERING
