Quote it from where you are sending.... Again quoting is the answer.


Example:

Process 1: Get and prints the argument.

Code:
$ cat get-arg.sh
echo $1 $2



File
: f1 is the file which has the given content

Code:
$ cat f1
products/100% Haddock Fillets  500G-small.gif
products/100% Haddock Fillets  500G.gif
products/2 Hot and Spicy  Grills 200G -small.gif
products/2 Hot and Spicy  Grills 200G.gif
products/2 Original  Fillet Burgers 180G -small.gif
products/2 Original  Fillet Burgers 180G.gif

Process 2: Reads lines, and calls the other process with the argument.

Code:
$ cat t1.sh
while read line
do
#echo $line
sh ./get-arg.sh "$line"
done < ./f1

Note: When "" around line is there then it had been taken as a single argument...

I hope you have got it now as because i demonstrated enough ....

If needed, give without QUOTE in $line, then you will printing only first two words...


With Quote:
Code:
$ sh t1.sh

__________________________________________________________________________________________________________________________________________________

NAME
concat - Join lists together SYNOPSIS
concat ?arg arg ...? _________________________________________________________________ DESCRIPTION
This command joins each of its arguments together with spaces after trimming leading and trailing white-space from each of them. If all the arguments are lists, this has the same effect as concatenating them into a single list. It permits any number of arguments; if no args are supplied, the result is an empty string. EXAMPLES
Although concat will concatenate lists, flattening them in the process (so giving the following interactive session): % concat a b {c d e} {f {g h}} a b c d e f {g h} it will also concatenate things that are not lists, as can be seen from this session: % concat " a b {c " d " e} f" a b {c d e} f Note also that the concatenation does not remove spaces from the middle of values, as can be seen here: % concat "a b c" { d e f } a b c d e f (i.e., there are three spaces between each of the a, the b and the c).
