Question awk Varing Field Separators

Hi Guys,

I have small dilemma which I could do with a little help solving . I currently have text HDD S.M.A.R.T report which I have pasted below:

I have written a small script to extract the few fields at the top of the report as show below which eventually gets saved as to a CSV file so I can import it into my database:


$1 ~ /^Device$/  {device = $2 $3}
$1 ~ /^Serial number$/     {ser = $NF}
$1 ~ /Device type$/     {devt = $NF}
$1 ~ /^Transport protocol$/ {tranp = $NF}
$1 ~ /^Local Time is$/ {time = $2 $3 $4}
$1 ~ /^SMART Health Status$/ {smrtstat = $NF}
$1 ~ /^Elements in grown defect list$/ {glist = $2}

END {print device "," ser "," devt "," tranp "," time "," smrtstat "," glist "," readeccf "," readeccd "," readrereadrewt "," readtoterrcorrec "," readcoralginvocat "," readgigpro "," readtotuncorerr "," writeeccf "," writeeccd "," writerewriterewt "," writetoterrcorrec "," writecoralginvocat "," writegigpro "," writetotuncorerr; exit}

This extracts the desired fields perfectly but.... I don't just want these feilds. My trouble starts when I begin to try and extract the data in the fields "read:" & "write:". I'm trying to extract the 7 columns individually so they appear in me csv file as

device, serial, etc.....0, 906, 155, 60, 0, 38098.027, 95.....

My problem seems to be that my field separator is set to a ":" and these fields are separated by blank space. Can I get awk to change the Fields Separator half way through my script? I'm a bit of a newbie to this but I'm picking it up pretty quick.

Any help would be gratefully appreciated.

Just a hint:
echo 'read:      0         906       155          60              0           38098.027     95'  \
| awk '{split($0, a); print a[2] "," a[3] ",..."}'

Hi yazu!!

Thank you for your promt reply, unfortunatly I don't belive this will work. I forgot to metion that this is just one report of many so obviously the data in the read fields verry from report to report. Thank you for your input though.

Ahhh I solved my problem by creating a seperate awk script to parse out the data using the following Feild Separator:
FS="[: ]+"

I then added a line to my bash script to compensate for this extra extraction and then merged my two output files together using sed. Its about as elegant as midnight bar brawl but it works for me.
