[SOLVED] How to take a int from 2 lines of text

Hey mates, when I do a logcat, i got lot of lines, that I filter with a grep, at end, I just got some lines like this:

Code:

I/ActivityManager( 1763): Config changed: { scale=1.0 imsi=732/123 loc=es_ES touch=3 keys=2/1/2 nav=2/1 orien=1 layout=17 uiMode=17 seq=15}

I/ActivityManager( 1763): Config changed: { scale=1.0 imsi=732/123 loc=es_ES touch=3 keys=2/1/2 nav=2/1 orien=1 layout=17 uiMode=17 seq=17}

but I only need the 17 that is after seq=, ignoring the 15 from the first code, and store it as a Int, so how can i do it?
PD: This is for android device, but problem is with programming not with SO

Well I guess the question to you would be how do we know to ignore the 15? I assume it may not always be 15 nor the other line always 17.

Or maybe the case is you always want the entry from the last line?

Until you are a little more clear it is difficult to assist.

I got lot of lines like that, lets assume 10, i wanna ignore the first 9, and only take the int from the last line, and yes, they will be not allways 15 and 17, maybe 1 and 3 or something like that

Code:

tail -n 1 log.txt | cut -d " " -f 15 | cut -d "=" -f 2 | cut -d "}" -f 1

Or

Code:

tail -n 1 log.txt | cut -d "q" -f 2 | sed 's/=\([0-9]*\)}/\1/'

I'm sure there's a simpler expression, but both of these work, and you get the idea.

Sometimes I use tac in certain situation to read the last entry (i.e. first entry from the file in reverse order) and exit from any script after a match.

Code:

awk -F"[={}]" 'END{print $(NF-1)}' file
