    Hi,

    I have a problem with the execution of a script in a script.
    I want recover a variable in a script and test this in a other .

    For exemple :
    A script : sc1.sh
    Code:
    #!/bin/sh
    var=3
    
    A script : sc2.sh
    Code:
    #!/bin/sh
    sh /folder/sc1.sh
    if [ var -eq 3 ]
    echo "goods"
    fi
    
    But this is bad.

    I try with export var , but it's not good too.
    Can you say me how can I do this?

    Thx.

    I try this
    sc1.sh :
    Code:
    #!/bin/sh
    var=1
    sh /folder/sc2.sh $var
    
    sc2.sh :
    Code:
    #!/bin/sh
    echo $1
    
    But The system didn't accept a variable in the command sh only a "word" (
    ex: sh /folder/sc2.sh var .

    Where is the problem?

    So if I understand you correctly, you want to pass one variable onto another script? Theres two ways that come to mind straight away:

    * Lets say the two scripts are in the same directory...
    Example 1
    ----------

    Script 1:

    Code:
    #!/bin/sh
    
    returnvar=1
    echo $returnvar
    
    Script 2:
    Code:
    #!/bin/sh
    
    # This should set $var to whatever script1 outputs.
    var=`./script1`
    
    echo Passed: $var
    
    Example 2:
    ----------

    Script 1:
    Code:
    #!/bin/sh
    
    returnvar=3
    #We are sending $returnvar as the first argument to script2
    ./script2 $returnvar
    
    Script 2:
    Code:
    #!/bin/sh
    
    echo Passed $1
    
    From my experience in a debian environment this would likely work, no idea what you are using, though none of this has been tested.

    Thanks, hope it helps.

    I'd do it like this:

    sc1.sh:

    Code:
    var=3
    sc2.sh:

    Code:
    #!/bin/sh
    . /folder/sc1.sh
    if [ $var -eq 3 ]
    echo "goods"
    fi
