CAT Command

ouncya · 08-21-2007, 03:32 PM

Hi Friends,

I have created file using CAT command. File name "-r". It accepted. When I tried to see the contents using the command " cat <filename>", I couldn't see. Can any one help me?

Try "cat -- -r"
And then maybe rename it; use the same trick.

hey friend,

Thanks a lot. It's working... :-)

Moral:
don't create files with funny names.

Another trick:
To access a file with a funny name, add the full path. In your example--eg: "cat /home/username/-r". This works for cat, mv, etc.

Pixellany,
Could you also use quotes around the filename, rather than the full path?

Another way to access files with funny names is to use a GUI file manager.

I am fuzzy on this...My comment is based on a situation posted here some months ago. The only solution that I could think of was using the full path.

I think it depends on what funny character gets into the funny filename...let's say you have a character that looks like an option to a command like mv or cp. Quoting won't help--because that only protects the funny character from bash.

Ok, here's one:
touch somedir/-R
This creates the file "-R" in somedir. Now go into somedir and try to make a copy.

I've found using single quotes works to rm or mv funny named files.

Neither single nor double quotes will work in my example. The key is that "-R" has special meaning to the cp command. any kind of quotes simply serves to insure that the "-R" gets to the cp command without bash interfering.

hey friends,

Is there any other way to open the file "-r" rather than "cat -- -r"?

Starting to sound like homework.

ouncya · 08-25-2007, 11:48 PM

hey friends,

I found another way.

cat ./-r

It works... :-)
