I have the following loop to read and set variables passed to a bash script
while [ $# -gt 0 ]; do
if [[ $1 == *"--"* ]]; then
param="${1/--/}"
declare $param="$2"
# echo $1 $2 // Optional to see the parameter:value result
fi
shift
done
For example one can call it via:
sh test.sh --name myname --family myfamily
How can I change it to call it as:
sh test.sh --name=myname --family=myfamily
You can use variable content substitution syntax in bash to "arrange" one argument in several substring. The first substring is -- (that you're already removing) the second substring will be the variable name, the third will be = and the last will be the variable content.
This can be done by a slight modification to your script:
while [ $# -gt 0 ]; do
if [[ $1 == *"--"* ]]; then
param="${1/--/}"
value="${param##*=}"
param="${param%%=*}"
declare $param="$value"
echo variable name: $param
eval echo variable content: '$'"$param"
fi
shift
done
This way, if I feed these parameters to the new script:
sh test.sh --name=myname --family=myfamily
I get the following output:
variable name: name
variable content: myname
variable name: family
variable content: myfamily
