Question

I have a issue with case sensitive directory listing in my bash. for example

   $ touch  nohupa nohuPb
   $ ls nohup*
   nohupa  nohuPb

However I do expect it only list nohupa not nohuPb. because nohuPb has capital P.
I don’t know what variable in my .bashrc set that * works ignore case.

Any idea ?

Answer 1

It’s nocaseglob that causes that.

nocaseglob
If set, bash matches filenames in a case-insensitive
fashion when performing pathname expansion (see Pathname Expansion
above).

testing

$ touch fooab fooAb
$ ls
fooAb fooab
$ shopt -s nocaseglob
$ ls fooa*
fooAb fooab
$ shopt -u nocaseglob
$ ls fooa*
fooab
