remove spaces from a input value

Hello,
I am trying to remove spaces from a input value to my script.  Need some help with the syntax,

for example,

number=$1
customer=$2
loaction=$3

newcustomer=$(awk '{gsub(" ","-",$2);print $2}')
echo $newcustomer

Thanks,

Do you really mean "translate spaces in awk's $2 (= field #2 of the input string, which may be the content of $customer ) to hyphens and store the result in newcustomer"? To make this work you'll need a field separator other than "space" in $customer, and you must put "$2" at the shell level between quotes.

customer="$2"

For bash:

newcustomer=$(awk -F"field_separator" '{gsub(" ","-",$2);print $2}' <<< $customer)

For ksh (works in bash as well):

newcustomer=$(echo $customer | awk -F"field_separator" '{gsub(" ","-",$2);print $2}')

But if you mean "translate spaces in $customer to hyphens and store the result in newcustomer":

customer="$2"

newcustomer=$(awk '{gsub(" ","-");print}' <<< $customer)

newcustomer=$(echo $customer | awk '{gsub(" ","-");print}')

Please remember that you must call your script like this (mind the quotes):

scriptname number "cus to mer" location

If "number" or "location" can contain spaces you must enclose the corresponding input values in quotes as well:

scriptname "num ber" "cus to mer" "locat ion"

If you are using bash you can remove spaces with:

    newcustomer=${customer// /}

or change spaces to hyphens with

    newcustomer=${customer// /-}

(Edit: changed to "newcustomer" to match existing examples)

If you want (or need) to use an external program, you are better off using the one designed to replace characters - tr

To replace spaces with hyphens:
    newcustomer=$(echo $customer | tr ' ' '-')

Open in new window

or to delete spaces:
    newcustomer=$(echo $customer | tr -d ' ')

Open in new window
