Bug Listing files in a Unix Directory ending with .....
Hi Unix Gurus,

I need to list all files in a Unix Directory which either end with a
.pdf or .rtf and they should be case insensitive ie .Pdf , .pDF , .RtF etc are also possible.

How can i accomplish this with with a ls command ? If not then a find command.

Alternative:
Code:
ls *.[pP][dD][fF] *.[rR][tT][fF]

@pamu: The dots should be escaped and the strings should be anchored..:
Code:
ls | grep -iE '\.pdf$|\.rtf$'

So Scrutinizer, which one is preferable?

Code:
ls *.[pP][dD][fF] *.[rR][tT][fF]

or

Code:
ls | grep -iE '\.pdf$|\.rtf$'

Thanks again.

Just choose what you feel most comfortable using on the command line or what is easier to use or remember. The first is more efficient, since it does not involve a subshell and an extra external program so that might matter in a scripted situation...

The ls version is preferred if you need to deal with more than a few dozen files.

The * version is preferred when the number of files is known to be small. It may fail with 'too many arguments' if the number of files grows too large to fit in one shell variable.
