wildcard character `* ` can't match some string?
Files which begin with a dot are hidden from file listings by default. The easiest way to match those kind of files would be to put a dot in the beginning of the expression. However, this will onyl match files starting with .
.
ls -al .*.swo
The alternative is to set the dotglob
before running the command, then files starting with .
will be included.
shopt -s dotglob
Add it to your ~/.bashrc
to set it by default.
Note that setting dotglob
can lead to uninteded results when using the bash shell, since both .
(current directory) and ..
(parent directory) will appear when using *
. With dotglob
set, never try to use rm -R *
.
As an extension to Shaido's answer I'd like to give some explanation why the -a
option will not work here:
The ls
command does not process wildcards. The command line interpreter does this step:
If you type the command line "mycommand *.c
" the command line interpreter will first replace the wildcard string "*.c
" by the list of matching files and then execute the resulting command line:
mycommand a.c file.c test.c
The command line interpreter works the same way for all commands so it cannot know that -a
means "including hidden files" in the case the ls
command (while -a
has a totally different meaning for other commands)...
