UNIX for Dummies Questions & Answers

Hi,

I need to get filenames without an extension using an ls command. is there a way to do that?

for example.
I want to get: abc_123_ggg
but not: abc_123_ggg.TXT

Anything would be appreciated.

Probably not what you wanted but it does work.

$ ls abc_123_ggg

Thanks for the reply, but yea, that's not what i wanted.

there are hundreds of files, and i need the file name for all of them that does not have the extension.

thanks..

Give examples of the file names -

If they are all the same length (files with and without extensions) then you can do a listing with a wildcard ? (instead of *).

example: all files have 8 characters and then the .ext

$ ls ???????

will only give you files with 8 characters (it does not care what those characters are)

If you pipe output from the ls command to grep, you can also find what you are looking for:

$ ls -1 *|grep -v \[.\]

ls in one column - search and show only lines not containing .

ls !(*.*)

Many Thanks RTM.

is there a way to do this without using grep?

and no, the filenames are not with the same name.

the ideal way i can do this is:
$ ls not *.txt = to find everything not end with .txt

Thanks.

taking this a step further...
can i view the files without an extension from another location?

ie.
$ more /directory/aaaa/*

but that will display everyfile. I only want to read the ones without the .txt extension?

possible?

Thank you.
