I can't reproduce this. I am running "grep (GNU grep) 3.11" and "xargs (GNU
findutils) 4.10.0" on an Artix distribution.
I have a directory that has 52422 regular files in it, over twice your example
with some 23397 files.
I get the same result regardless of whether or not I constrain xargs to "-n
100" arguments per exec.
Could you:
1) See if you can see any difference in if or how xargs invokes grep on the two
files that are coming up different, by looking for those two missing filenames
in the tracing output from using the xargs --verbose option.
2) Probably not helpful, but is there anything strange about these two missing
files:
< ./apex/images/apex_ui/psd/apex_5_ui.ai
< ./apex/images/apex_ui/psd/apex-logo.ai
Are their sizes and file types, from the 'file' command, similar to some of
the other files?
My wild guess speculation would be that you're hitting some unknown limit on
xargs when invoked with an argument list that is right at the limit of what
your system allows. But I wouldn't bet a cheap beer on that guess being right.
