How to pass a parameter with double quotes around it to a command
In a bash script, I need to pass a parameter that has space in-between using double quotes as follows:

Code:
CMD="SomeExecutable"

# Parameter that has a space in-between
Code:
PARAM1="TIMO 2"
 
CMD_IN="--name=\"$PARAM1\""
 
CMD_OUT=`$CMD $CMD_IN`

expected/required command execution:
Code:
SomeExecutable --name="TIMO 2"

But, what i see is:
Code:
SomeExecutable '--name="TIMO' '2"'

Why? How do I fix it ?

Thank you!

Thanks for the response.
Are you suggesting

Code:
CMD="SomeExecutable"
CMD_IN='--name="TIMO 2"'
CMD_OUT=`$CMD $CMD_IN`

Still, I get the following

Code:
SomeExecutable '--name="TIMO' '2"'

Not what is required (SomeExecutable --name="TIMO2")

Hi.

I get the right answer:

Code:
$ cat SomeExecutable
echo SOME EXECUTABLE HERE
echo ARGS ARE
echo $@

$ cat T1
CMD="./SomeExecutable"
CMD_IN='--name="TIMO 2"'
CMD_OUT=`$CMD $CMD_IN`

echo $CMD_OUT


$ ./T1
SOME EXECUTABLE HERE ARGS ARE --name="TIMO 2"

Thank you. It works now with minor adjustment as follows:

If the SomeExecutable is like this

Code:
$ cat SomeExecutable
echo SOME EXECUTABLE HERE
echo ARGS ARE
echo "P1="$1
echo "P2="$2

Then the output is,
Code:
SOME EXECUTABLE HERE ARGS ARE P1=--name="TIMO P2=2"

Fixing that required the following:

Code:
$ cat T1
CMD="./SomeExecutable"
CMD_IN='--name="TIMO 2"'
CMD_OUT=`$CMD "$CMD_IN"`
 
echo $CMD_OUT

Then the output is,
Code:
$ ./T1
SOME EXECUTABLE HERE ARGS ARE P1=--name="TIMO 2" P2=
