android - Finding substring at the end of line in shell -

-

i new shell scripting.

when write adb shell ps | grep "org.mozilla.fennec"

u0_a52    908   57    557664 144820 ffffffff b6f755cc s org.mozilla.fennec

and 

u0_a52    1083  57    243108 23824 ffffffff b6f755cc s org.mozilla.fennec.updateservice

the problem need first line. tried adb shell ps | grep "org.mozilla.fennec$" surprisingly shows nothing.

i need second field of first line. how can using grep? appreciated. thanks.

to print 2nd field can use awk:

adb shell ps | awk -v rs='\r' '$nf == "org.mozilla.fennec"{print $2}'

to print whole line:

adb shell ps | awk -v rs='\r' '$nf == "org.mozilla.fennec"'
