pattern searching

Hi,


Can you please help me out here? I am trying develop a search pattern to extract certain words from the two strings below.

I want to extract ericsson_msc_live from the 2 strings and then the date, which is a part of the filename just before the .jar extension.

ericsson_msc_live_bln_western1_20120809.jar

ericsson_msc_live_bln_western_20120711.jar

I am able to extract ericsson_msc from string below using awk and '_live' as the delimiter, but then it doesnt give me the full name so I have to append '_live' as a print statement. Using sed I am able to extract only numbers from the strings but then again it doesnt give me the correct output as western1 is also a part of the file name




Looking forward for some advice

Thanks

Code:
Provide the details about the output and it's format, when you are giving the file names as input.

Code:
ls -1 *.jar|awk -F "_live" '{print $1"_live"}'

gives me output as ericsson_msc_live

and the below gives me the date (or only numbers in the string)

Code:
ls -1 *.jar|awk -F "_live" '{print $2}'|sed "s/[^0-9]//g"|awk '{print substr($0,1,8)}'

but the problem is, the above command gives me this too 12012072, which is not the date because the string contains 'western1_20120809.jar' also

hope that helps

If all files under the directory in the same format u can try

Code:
 
for filename in *.jar ; do
basename $filename|sed -e 's/_bln_western1//g'
done

Dear Vidya,

thats the problem..all files are not in the same format. i have mentioned it in the previous post:


ericsson_msc_live_bln_western1_20120809.jar

ericsson_msc_live_bln_western_20120711.jar

then you have to try something like

Code:
ls -1 *.jar|awk -F"[_.]" '{print $1"_"$2"_"$3"_"$(NF-1)}'

Hope this is what you are expecting.
Code:
for file in ericsson_msc_live_bln_western1_20120809.jar ericsson_msc_live_bln_western_20120711.jar
do
echo "$file" | sed -n 's/\(ericsson_msc_live\).*\([0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9]\).*/\1\2/p'
done

Code:
ericsson_msc_live20120809
ericsson_msc_live20120711
