Please do not tag threads as urgent, all responses here are made by volunteers in their own free time. I don't see anything urgent about your request to begin with.. Not like you have a server that crashed or something, not that that would make a difference..

so it looks like you want to sort based on a pattern of some kind ? Like list all the files that begin with abc ? heres a command for you apropos. Apropos searches the manual pages descriptions for the term specified and returns commands that meet that search criteria.. then you can view their man pages for further info..

apropos pattern will give you a list of commands used for pattern matching. Things such as grep, awk, etc..

more detail on what you are trying to show in your results, would be helpful to get a more useful answer..

look at the --ignore flag on the following man page:

http://linux.die.net/man/1/ls

unlike the --hide flag, --ignore is not overridden by -a

I've edited the thread title. In the future please avoid using "urgent", "help me" and other titles that do not describe or summarise your problem. Good thread titles help increase the exposure of your thread.

I don't see the purpose in making a filename hidden to the point it can't be seen by ls -a, unless you are working on writing a rootkit...


What exactly are you trying to accomplish and why ???

I am trying to implement a new function to retrieve the files which are deleted, trying to sort of use a trash bin for the deleted files and retrieve it back.the files in the bin should not be visible to user so im implementing it.

Thanks

Of course I can't stop you from re-inventing wheels, but unless
you're very good they may turn out square, or with an off-centre
axil ... oh well. Anyway: you can't hide a file from ls' all-together
unless you hack ls in a way that makes it ignore files e.g. with
a special non-printable character. Bad idea, though.



Cheers,
Tink

man ascii
anything smaller 0x1F, for example ... of course there's
not just 'ls' you'd need to hack. There's bash (with it's
TAB expansion and globbing), there's 'mc', maybe some GUI
tools like Konqueror, Nautilus, .... if I were you I'd
abandon the idea rather quickly :} and move on to known
tools and some user training ;}


Cheers,
Tink
