How to pass parameters from ruby file to shell script file

Ruby
1

In shell script file im having list of linux commands…when running
script.sh file, second command (in script.sh file)it will ask user to
specify some details.I can specify these values when i run script.sh
file,while im running script.sh file in Terminal using sh script.sh.
But if i run script.sh file from ruby using exec"sh script.sh",i can
type in terminal…so i have to specify these values in ruby file
itself…
how to pass parameters from ruby file to that script.sh file?

This will actually read from stdin.

By typing, yes.

You can type in terminal when invoking the script with exec.

13:47:30 ~$ dash -c “read -p input: l;echo got $l”
input:abc
got abc
13:47:35 ~$ ruby19 -e ‘exec “dash”, “-c”, “read -p input: l;echo got
$l”’
input:def
got def

so i have to specify these values in ruby file itself…

I do not think so (see above).

Passing parameters is a different story: parameters (aka “command line
arguments”) are passed with the execution, e.g.

13:42:30 ~$ time ruby19 -e ‘exec “/bin/sleep”, “5”’

real 0m6.150s
user 0m0.139s
sys 0m0.124s
13:42:40 ~$

So, what is your problem?

Kind regards
