Re: listing files with spaces, using wildcard

i thought simply doing somehting like

 ls '*foo_*.dog' and surrounding the filename with single quotes would
work.. but it doesn't.



This is fundamental:

the command: ls, does not take wildcards.
The shell expands wildcards and passes the results to ls.

By quoting the wildcards, you are passing them to ls to interpret, which it cannot.

The command, find: DOES accept wildcards for some arguments, like: -name. Thus, you want to pass wildcards to the find command by quoting or escaping them.

Also, the shell treats the double quote marks: " differently than the single quote marks: ' under certain circumstances.

The 'convention' for quoting is:

double quotes for passing wildcards

single quotes for strings that may contain other characters that the shell might interpret. But even then, it may depend on the command you are passing those arguments to.

For example, neither will allow you to pass a minus character, as the first character of a pattern match, to grep.

In your original work here, the first line you typed works:
ls *foo*dog
Even with spaces.

Your other attempts using quotes do not work because you are passing the wildcards to the ls command, which cannot use them.

Hope this helps!
