Bash assistance

Hi. I'm not sure how to create 2 variables that I need to create.

I'm setting this variable:
variable="domain.tld/user"

From that, I need $variable split into 2 other variables (splitting at the slash). A "$domain" variable and a "$user" variable.

Is this possible?

as ever there are a trillion ways to do this, try awk:

variable="domain.tld/user"
domain=$(echo $VAR | awk '{split($0,a,"/"); print a[1]}')
user=$(echo $VAR | awk '{split($0,a,"/"); print a[2]}')

i'm sure sed and/ord grep can do it too, no problem.

Another method is using cut:

variable="domain.tld/user"
domain=`echo "$variable" | cut -d"/" -f1`
user=`echo "$variable" | cut -d"/" -f2`

Simpler and faster (no external programs are run, bash internal):

Code:

variable="domain.tld/user"
domain=${variable%/*}
user=${variable#*/}

echo Domain: $domain
echo User:   $user

All built-ins

Code:

SF1B : /supmis/soumen/tmp > cat st
variable="domain.tld/user"
set `IFS=/ ; echo $variable`
domain=$1 ; user=$2
echo "[domain:$domain user:$user]"
SF1B : /supmis/soumen/tmp > sh st
[domain:domain.tld user:user]
SF1B : /supmis/soumen/tmp > ksh st
[domain:domain.tld user:user]
SF1B : /supmis/soumen/tmp > bash st
[domain:domain.tld user:user]
SF1B : /supmis/soumen/tmp >

Except

Code:

SF1B : /supmis/soumen/tmp > csh st
variable=domain.tld/user: Command not found
set: Syntax error
SF1B : /supmis/soumen/tmp >

Good fun.

HTH.
