vi/sed/awk quetsion

[Edgar_10]

Hi,

I have a file containing 5 fields($1-$5) and I want to insert in the beginning of $2 & $3 a "0".Anyone know how best to do this in vi/sed/awk?


Thanks!

Hi,

No worries, sorted issue, I will do following:

cat file| awk '{print $1,"0"$2,"0"$3,$4,$5}'

Thanks!

Hi Dean,

Best to keep it simple, just use:

# cat file|awk '{print $1, 0$2, 0$3, $4, $5}' > newfile

Regards,

James.

Hi,

If the fields $2 and $3 have some pattern that vi can handle you can do it with vi, is quicker than other methods.

On the other hand you can do it with awk like this:

awk '{printf("%s 0%s 0%s %s %s\n", $1,$2,$3,$4,$5)}' file_in > file_out

and rename the file_out to file_in

I assume the separator filed is the space bar.
