Well, shooting in the dark, try
while IFS=, read NR SC; do [ "$NR" != "" ] && { ((NR+=100*(SC-${OLDSC:-$SC}))); OLDSC=$SC; echo $NR,$SC; } || echo; done < file

Try (untested)
awk 'NR == 1 {last = $1} {print $0, $1 - last}'

If a value is an exact integer, awk strips decimals by default. Use printf in case you want decimals.

perl -lane 'print ($F[1]+$F[2])*$F[3]' inputfile

Try:

awk '{ printf "%f\n",$3*($1+$2)}' filename

Divide by 1000 ?

awk 'NF{print $1/1000}' OFMT="%.5f" file

I don't understand.

Place the whole command to watch within single coma.
watch -n1 'command /dev/x | cat >> output'
However, the command cat it not necessary there.

Hi Board27,

Why can you not simply do a "make clean" in your build directory and then create a tarball of the build directory for copying to the other system?

Depending on your OS and the shell you use, this might work:sox $(ls -t /direxample/*.wav| head -1) -n spectrogram will always use the latest file in that directory.
