I have a file which is named “-l”, and I use the wc to count the file, undesirably wc requested the standard input rather than my file "-l" ,although I use it through the command

wc -lw -l

it didn't work as my will, however, linux itself do not limit this kind of name style, but wc does, so unreasonable, such as my above command actually doesn't cause a ambiguity, so can you improve it ? try to check whether those files exist by the args from arg[2] atleast,not ignore those arguments.

 

expect your reply.:)

 

 

 

Cheers,

JameDam

Try either of:

wc -lw -- -l
wc -lw ./-l

This is not a bug in wc.  Rather, it is a FAQ:
https://www.gnu.org/software/coreutils/faq/coreutils-faq.html#I-have-a-file-called-_002d_002dhelp_002e-How-do-I-remove-it_003f

And like most utilities, using an explicit -- to mark the end of
options, or spelling your file name with a leading ./ so that it can't
be confused with an option, will do the trick.

Therefore, I'm closing this as not a bug, although you should feel free
to add any further comments or questions to this thread.
