part of a filename

flame_eagle · #1 (**permalink**) 02-27-2008

Hi,

I need to extract only a part of the filenames of some files. The files are named this way :

Code:

.tap_profile_SIT02

I want the "SIT02" part, which is not the same for each file. I was able to get what I want with bash, but not with ksh. Here is the command I used in bash :

Code:

find .tap_profile_* | grep -o "[A-Z]\{3\}[0-9]\{2\}$"

slight modification to your command

Quote:

find . -name '.tap_profile_*' -print | grep "[A-Z]\{3\}[0-9]\{2\}$"

where "." (dot) specifies the command to find from current directory

I'll do the modification later, it never hurt to be more rigorous

Also, to make things clearer, let's say there is a file named ".tap_profile_SIT02old", I don't need it in the resulting file

Try this with sed:

Code:

find .tap_profile_* | sed 's/.*_\(.*\)/\1/'

Code:

find .tap_profile_*
.tap_profile_DEV07
.tap_profile_DEV07_6.2.1.0
.tap_profile_DEV08
.tap_profile_GFER1
.tap_profile_SIT02

Code:

find .tap_profile_* | sed 's/.*_\(.*\)/\1/'
DEV07
6.2.1.0
DEV08
GFER1
SIT02

That's why I was trying with a regular expression, not that your idea wasn't a good one.

@bobbygsk

I tried your modification, but the result I get aren't the same. It matches a lot more files

I have not read your 2nd post before I post the solution, try this with awk:

Code:

find .tap_profile_* |awk -F"_" '{print $3}'

Regards

flame_eagle · #7 (**permalink**) 02-28-2008

Code:

find .tap_profile_* |awk -F"_" '{print $3}'
DEV07
DEV07
DEV08
GFER1
SIT02

I'm still getting results that I don't need (.tap_profile_DEV07_6.2.1.0 should be ignored)
