In a bash script, we can escape spaces with \ . Is there any way to do the same from code?
$ a=hello\ world
$ echo $a
hello world
$ b=${a:?} # ? used as dummy; it will not work
$ echo $b
hello\ world
caller.bash
#!/bin/bash
name=$1
if [[ -n $name ]]; then
where_query="--where name $name"
fi
mycommand $where_query
mycommand, an external program, we cannot modify. Dummy code added only for illustration purposes.
#!/bin/bash
for i in "${@}"
do
echo "$i"
done
Actual
$ caller.bash "foo bar"
--where
name
foo
bar
Expected
$ caller.bash "foo bar"
--where
name
foo bar
