Not using the -l option saves you from nearly all of the gyrations having to do with extracting the information that you do want. Just drop the -l and the script becomes significantly simpler.
Actually, you could simply use echo with a wildcard and look at the result. Depending on your shell and its settings, the result when the wildcard doesn't match can be either an empty string, or the wildcard expression unexpanded. If it's anything else, the file is there, and the result is the result of the wildcard expansion.

Reason: Fixed embarrassing typo
I'm trying to delete lines from a large text file using VI.
Every line that I am wanting to delete start with 'S' - all others do not. (A list of users)
I've tried using * but doesn't seem to like it...any ideas...
Doesn't have to be VI - but I'm better with VI than sed/awk. (8 Replies)

Hi All
Please excuse another straightforward question. When creating a tar archive from a directory I am attempting to use wildcards to eliminate certain filetypes (otherwise the archive gets too large). So I am looking for something along these lines.

Hello all-
First post, so just to forewarn you: I know enough about Perl and the Terminal to get myself into trouble, not quite enough to always get out.
I'd like to know if it is possible to, from the command prompt, use a wild-card to declare the names of files for input and then use the... (1 Reply)
I am using the following command to check for files on a Unix (Solaris 9) and on Linux:

If no las file is present, the "no las file found" message is displayed. If a las file is present, however, I get... (9 Replies)

These 2 websites do a GREAT job of explaining different types of wildcards. I learned about the categories of characters which I never knew about at all.

Does anyone know how I would go about inserting text at the beginning of a file with the file name containing a daily time stamp? Essentially I need to find the file name using a wild card, and then insert 3 lines of text - one of which is the processing date. Help please!? (1 Reply)
I have four files:
test
test2
test3
test4
I have this simple script:
#!/bin/bash
ls $1
Why does ./the_script.sh test* only list the first file, when a normal ls test* would list all four? What do I need to change in the script to be able to use wildcard? (12 Replies)
