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
