Renaming a file
I am a complete Unix newbie and I need some help! (Please...)

I need to rename a file from the following format:
Test_Test_EAR_1234.ear

To the following:
Test_Test_EAR.ear

In other words, I need to remove everything after & including the final underscore up to the "." What is the best way to go about doing this? Any help would be greatly appreciated. Thanks!

You can use sed to make the change, something like this:

namefilename=echo $filename | sed -e 's/_[^.]*(\.[^._]*)/$1/'`

you mean you want to remove whatever present between last "_" and "." right???
this will help
Code:
mv Test_Test_EAR_1234.ear `echo Test_Test_EAR_1234.ear|sed 's/\(.*\)\(\_.*\)\(\..*\)/\1\3/g'`
mv anyfile `echo anyfile|sed 's/\(.*\)\(\_.*\)\(\..*\)/\1\3/g'`

Thanks, CRGrathouse, but I need to do this via an automated Unix shell script. The list of files and the numbers I need to remove will be variable.

vidyadhar85, the following works like a charm! Thank you SO much!

mv Test_Test_EAR_1234.ear `echo Test_Test_EAR_1234.ear|sed 's/\(.*\)\(\_.*\)\(\..*\)/\1\3/g'`

Don't suppose you could explain how the expression works?

You may build using shell variable too, under "bash" or "ksh" they work the same.
Code:
X=Test_Test_EAR_1234.ear
XExt=${X#*.}
XNoExt=${X%.*}
XNewBody=${XNoExt%_*}
XNew=${XNewBody}.${XExt}
echo $X $XNoExt $XExt $XNewBody $XNew
unset XNoExt XExt XNewBody
echo mv $X $XNew

Just delete the "echo" on last line and you may change name to you file. The output for this command would be
Code:
Test_Test_EAR_1234.ear Test_Test_EAR_1234 ear Test_Test_EAR Test_Test_EAR.ear
mv Test_Test_EAR_1234.ear Test_Test_EAR.ear

Yes I know is a little big for you all guy may be used to. But this would be the way I would do it.

My best regards to all

Code:
name="Test_Test_EAR_1234.ear"
echo ${name%_*}.ear

or a more applicable one:

Code:
IFS="\."
name="Test_Test_EAR_1234.ear"
set $name
echo ${1%_*}.$2
