Help needed - Replacing all date & time occurrences in a file with a string using Sed

Shell Programming and Scripting
1

Hi,
I am new to using Sed. I have a file containg lines like the following:

INFORM----Test.pc:168:10/11/05 12:34:26 > some text goes here..

TRACE-----Test.pc:197:10/11/05 12:34:26 > some text goes here..

My requirement is to replace 10/11/05 12:34:26 with a string <RUNDATE> (including < & >).

Can anyone help me how to acheive this using Sed? I need this urgently..

I have tried this:
cat test.result | sed -e 's/[A-Z,a-z,-,_]\.pc[0-9,-,_]/\[A-Z,a-z,-,_]\.pc\<RUNDATE\>/' > test.result.tmp

But, it's not working.

Look at this

sh-2.05b$ echo "INFORM----Test.pc:168:10/11/05 12:34:26 > some text goes here.. " | 
sed -e 's#\(.*\)[0-9][0-9]/[0-9][0-9]/[0-9][0-9] [0-9][0-9]:[0-9][0-9]:[0-9][0-9]\(.*\)#\1<RUNDATE>\2#g'

INFORM----Test.pc:168:<RUNDATE> > some text goes here..

Overall it will be as

sed -e 's#\(.*\)[0-9][0-9]/[0-9][0-9]/[0-9][0-9] [0-9][0-9]:[0-9][0-9]:[0-9][0-9]\(.*\)#\1<RUNDATE>\2#g' test.result > test.result.tmp

Hi Vino,
Once again thank you very much for your help. And as I am new to Sed, can you please explain the command that you have given to me or Also, can you please point me to some good sites where I can learn Sed?
It is working very well, but want to understand its working. I understood little only.

   And here is one more problem I am facing, again I need your help:

Error: The directory /logDir/AR_archive/20051116135822 is not writeable

Error: The directory /test/logDir/AR_archive/20051116135822 is not writeable

I need to re-write as:
Error: The directory <AR_archive> is not writeable

I am trying the following:
sed -e 's#\(.*\)[AR_archive]/[0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9]\(.*\) #\1<AR_archive>\2#g'

But, it is giving:
Error: The directory /psg/gnanduri/Banksys/logDir/AR_archiv<AR_archive> is notwriteable.
