[SOLVED] sed, or better awk - find text and append it to end of line

[cantab]

OK, so I have a file that's a list of filenames. Each of these has a single numeric value in it, easily matched by

[0-9]+[.][0-9]+

I then want to append this to the end of the line, with a space seperator. How do I do this?

Re: sed (or otherwise) - find text and append it to end of line

Without knowing the format of the lines in your file I can't tell whether there is a simpler way, but

awk 'match($0,/[0-9]+[.][0-9]+/) {print $0, substr($0,RSTART,RLENGTH)}' inputfile_name > editedfile_name

should do it

Thanks. I spoke to IRL friends and one suggested awk as a better tool for the job. Mine is a bit different, mainly because I wasn't sure if I could put the substr command in the print statement, and also the requirements changed to comma seperated.

/[0-9][0-9]*[.][0-9][0-9]*/ {match($1, /[0-9][0-9]*[.][0-9][0-9]*/)
temperature = substr($1, RSTART, RLENGTH)
print $1","temperature",""c"
}
