Issue passing parameters to /bin/sh -c

Question

I am trying to use /bin/sh -c to execute a .sh script with a date parameter. The -c option is not optional as it's what the framework my team has uses. I can't get the date epoch parameter to pass to my script properly. The following is an example demonstrating how calling a file causes the parameters not to work whereas passing a command directly works fine. The middle command (without the -c) is the expected output with each number repeating.

root:xxxxx@xxxx:/opt/xxxxxx/software_versions> /bin/sh -c /opt/xxxxxx/software_versions/test2.sh 1 2 3 4
1
2
3
4
root:xxxxx@xxxx:/opt/xxxxxx/software_versions> /bin/sh  /opt/xxxxxx/software_versions/test2.sh 1 2 3 4
11
22
33
44
root:xxxxx@xxxxx:/opt/xxxxxx/software_versions> /bin/sh -c 'echo $1 echo $2' a b c d
b echo c

Script contents:

echo 1$1
echo 2$2
echo 3$3
echo 4$4

Answer 1

Your first example would work just fine if you called it as

software_versions> /bin/sh -c "/opt/xxxxxx/software_versions/test2.sh 1 2 3 4"

By using -c, you invoke a subshell to run the command that follows it. Additional arguments will not be passed to the subshell in any predictable fashion. You solve this by sending the full string as an argument.
