Shell Programming and Scripting

I have a tab delimited file with 4 fields.
I need to surround each field with a " (quote).
example:
K112 E-3433 SHOE REPAIR KIT 3
K119 E-1887ASHD SHOE REPAIR KIT 6
K128 E-2769SHD SHOE REPAIR KIT 3
K128K E-2769HD & SHD SHOE REPAIR KIT 15

needs to be:
"K112" "E-3433" "SHOE REPAIR KIT" 3"
"K119" "E-1887ASHD" "SHOE REPAIR KIT" "6"
"K128" "E-2769SHD" "SHOE REPAIR KIT" "3"
"K128K" "E-2769HD & SHD" "SHOE REPAIR KIT" "15"

don't care if it is a script or a command line command.
Just don't know how to do this.


Any help would be greatly appreciated.
Thanks.

Code:

sed 's/\([^ $]*\)/\"\1\"/g' < oldfile > newfile

Thanks for the prompt response.
I tried this command but I got this result:
"K112 E-3433 SHOE""" "REPAIR""" "KIT 3"
"K119 E-1887ASHD SHOE""" "REPAIR""" "KIT 6"
"K128 E-2769SHD SHOE""" "REPAIR""" "KIT 3"
"K128K E-2769HD""" "&""" "SHD SHOE""" "REPAIR""" "KIT 15"

I need it around just each field.
Thanks.

Code:

sed 's/[^ ][^ ]*/"&"/g' myFile

naah.... this won't work.
You need to define what's your 'field'.
Looks like your fields are NOT space separated.

Code:

awk 'BEGIN { FS = "\t" ; q="\"";  OFS = q FS q }
{ $1 = $1; print q $0 q }'  oldfile >newfile

This means that you have a BDS sed.

Code:

sed  -e 's/\([^ $]*\)/\"\1/g' -e 's/$/\"/' < file.txt > newfile.txt

I'm trying to thing of a cleaner way of doing this and will update when I do.

awk version: ( but I like futurlet's one better )

Code:

awk '{for (i=1; i<=NF; i++) { $i="\""$i"\"" }; print}' oldfile.txt > newfile.txt

Thanks Futurelet !
You guys are Geniuses.
I appreciate it.
a small favor?
I'm a newbie at this and your script worked, yet I don't understand it.
Could you break it down a little for me?
