Sorry for a newbie question but i have a file that looks like this and wanted to capture a line after a certain string which is /aggr.
/aggr0_usts_nz_3001/plex0/rg0:
9g.10.0 0 4.08 0.00 .... . 4.08 1.00 41 0.00 .... .

1a.10.1 0 0.00 0.00 .... . 0.00 .... . 0.00 .... .

9a.10.14 4 941.44 941.44 1.61 111 0.00 .... . 0.00 .... .
i wanted to take out a certain line after say for example /aggr0 and redirect it to a file. so sample would be, file1 will have this information
/aggr0_usts_nz_3001/plex0/rg0:
9g.10.0 0 4.08 0.00 .... . 4.08 1.00 41 0.00 .... .
1a.10.1 0 4.08 0.00 .... . 4.08 1.00 10 0.00 .... .
9g.10.4 0 4.08 0.00 .... . 4.08 1.00 49 0.00 .... .
1a.10.1 0 0.00 0.00 .... . 0.00 .... . 0.00 .... .
9g.10.4 0 0.00 0.00 .... . 0.00 .... . 0.00 .... .
and then file2 would be this information and so on.
/aggr1_usts_nz_3001/plex0/rg0:
1e.00.0 0 0.00 0.00 .... . 0.00 .... . 0.00 .... .
9o.01.44 0 0.00 0.00 .... . 0.00 .... . 0.00 .... .
1e.00.1 4 994.04 994.04 1.44 119 0.00 .... . 0.00 .... .
9o.01.41 4 981.91 981.91 1.41 141 0.00 .... . 0.00 .... .
1e.00.4 4 811.19 811.19 1.14 149 0.00 .... . 0.00 .... .
9o.01.14 4 809.99 809.99 1.14 119 0.00 .... . 0.00 .... .
1e.00.1 4 980.86 980.86 1.19 144 0.00 .... . 0.00 .... .
9o.01.11 4 998.89 998.89 1.11 140 0.00 .... . 0.00 .... .
so it’s like segregating the information on the file.
had this command below but since lines after aggr are not the same, it will only show what was defined (which is 7)
for i in `cat sample.txt`; do
echo $i | grep aggr* -A 7
done
but it’s only showing what I grepped.
this command here prints 2 lines after matching the pattern however what i want is to redirect it to a file.
awk '/aggr/{x=NR+2}(NR<=x){print}' sample.txt
any idea how can I accomplish it.
>Solution :
You may use this awk:
awk '/^\/aggr/ {close(fn); fn = "file" ++fNo ".txt"} {print > fn}' file
