Re: repeat data at one line and grep as pre-set format

I think you want to split each pair of data points out to a line on its own instead of having multiple datapoints on one line.

cat yourfile.txt | perl -ple 's/(\S+\s+\S+)\s+/$1\n/g'

should do this for you as long as you have even numbers of datapoints on each line

echo "00000001  99888  00000011  99889  00000002  99890  00000003  998
+08" \
| perl -ple 's/(\S+\s+\S+)\s+/$1\n/g'
00000001  99888
00000011  99889
00000002  99890
00000003  99808

`cat yourfile.txt \| perl -ple 's/(\S+\s+\S+)\s+/$1\n/g'` [download] Isn't that the same as: `perl -ple 's/(\S+\s+\S+)\s+/$1\n/g' yourfile.txt` [download] UUOC. Dave	[reply] [d/l] [select]

You are right and your way is more efficient too. I wrote it with the `cat file \|` as that is how I tested it with echo, just failed to engage my brain completely :-) Cheers, R. Pereant, qui ante nos nostra dixerunt!	[reply] [d/l]
