Hello,
I have an output from GDB with many entries that looks like this
0x00007ffff7dece94 39 in dl-fini.c
0x00007ffff7dece97 39 in dl-fini.c
0x00007ffff7ab356c 50 in exit.c
0x00007ffff7aed9db in _IO_cleanup () at genops.c:1022
115 in dl-fini.c
0x00007ffff7decf7b in _dl_sort_fini (l=0x0, maps=0x7fffffffeab0, nmaps=4,
used=0x4 <Address 0x4 out of bounds>, ns=0) at dl-fini.c:115
0x00007ffff7ab3570 50 in exit.c
74 in exit.c
How can I count how many times "in exit.c", "in dl-fini.c" and "in genops.c" is in the file?
It shouldn't count "at+...", only "in+...".
The output has to be
3 in exit.c
2 dl-fini.c
Why not grep -c "in exit.c" inputfile and the likes?
Because it'spart of a bigger awk script, and I need it in arrays.
I also want a nice output file.
Try this script:
awk '
BEGIN{A[1]="in exit.c"; A[2]="dl-fini.c"; A[3]="in genops.c"}
{for(i in A)if($0~A)B++}
END{for(i in A){print B"\t"A}}' gdb_output

Thanks, that works, but only for these 3.
After the "in", it can be anything...
I now have:
/in /{
count[$NF]++
}
END{
for(j in count)
print j "("count[j]")"
}
It works, but as you can see, it's not always the last field.
It's the field after "in". How can I define the arrays?
Here is a part of the source file:

You can add more in something in the BEGIN{} block code. Sorry, I can't help you much more =/
