Hi there,

I am writting my very first shell script, and I do not understand
why this does not work:

if diff gdcmData.tar.gz current.tgz >/dev/null
then
echo "There is a diff, need to upload"
else
echo "There is no diff no need to upload"
fi

when run in a shell script the 'else' is executed, while from the
command line I can see that there is a diff, so the return value is !=
0

thx

I'm looking for files in a directory hierarchy that have filenames
such as:

one.two.three.ext

but specifically those that have more than one dot in the name.
This is what I tried but it didn't work (it found one but not all --
inexplicably):

find . -name "*.\.*.\.*"

What do I need to change to get this to work?

Thanks.

Hello,

is it possible to rename the sub process of a shell?

Example: assume there's a script foo.sh which starts a background
process (kept simple here just to get a nice example)

#!/bin/sh
(sleep 20; sleep 10)&
echo "exiting $0"

when you check the process tree you'll find
UID PID PPID C STIME TTY TIME CMD
andy 125 124 0 13:26:29 pts/54 0:00 sleep 20
andy 124 1 0 13:26:29 pts/54 0:00 /bin/sh foo.sh
(this is on Solaris)
i.e. there is a sub process named after the originating shell script.

Instead of seeing /bin/sh foo.sh in the process table I would like
to have some other name, say foo_child, to appear.
Is that possible?
The example is a Bourne shell script, maybe another shell would do?

Of course I could put the code into a separate file and call that but
that is not what I want , it's basically about renaming $0 on the fly.

Hello all,
when I have a file that is hard linked multiple times, how can I find which
directory entries are the other links ?

I believe for soft links, the answer is "you can't unless you do an complete
search on all mounted filesystems". But I'm sure there's a simple solution
for hard links, right ?

How to extract everything up to and including the first number of each
line of a file?
e.g.
input is:

SECURITY SERVICES CANADA $26.50 ...
Jan. 02, 2008 Electronic Funds Transfer PREAUTHORIZED DEBIT TD

Hi,

I don't understand why bash also use // to represent root. Shouldn't
bash only show the canonical form '/'? Is it a bug in bash? Or it is
supposed to do that?

Thanks,
Peng

Hi,

When I paste any content in vi editor it is taking lot time. Its
happening if the paste content is having braces (). after it displays
closing brace ")" in screen the cursor is going back to the respective
opening brace.

Any idea how to get rid of it. This is happening in HP unix.

Thanks in advance,
