Data bad interpreter when running script

Hi All,

I'm not confortable in writing script, can someone can help me, when I run that script below i found this error code : -bash: ./script.sh: /bin/sh.: bad interpreter:

Here is the script

Code:
for i in *

        x=${i##*.}
        z=$(perl -e 'print time;')
        t=$(echo $z-$x|bc)
        r=test_file.$x


        if ((t>>86400))
        then tar -cvf $r.tar $r
                echo $i
                echo $z
                echo $x
                echo $t
                echo $r
                fi
        done

Regards

few things to check
1. if /bin/sh is available
Code:
 ls -l /bin/sh

2. have set eXecute permissions
Code:
chmod 755 script.sh

Done but same error,

In my opinion there is something wrong with the test : "if ((t>>86400))"

There are a few issues, starting with the fact that you didn't post the whole script. Especially the "bad interpreter" problem indicates an error in the "shebang" line defining the interpreter, and that line is missing altogether.

Second, the quotes if condition: are you attempting to say "much larger than", or a shift-right by 86400?

The traduction is, after bad interpreter : missing file or directory.

- I'm get confuse, the expression ((t>>86400)) try to put the value of "t" into 86400 file, but my wish is to test "t" to know that if "t" is greater than 86400.
Apologize, I'm french.
Regards.

Can you please post the complete script, including the very first line, which should look like this:
Code:
#!/bin/sh

The comparison fails for a very simple reason: the brackets you're using (>>) are used for redirection, not comparison. The proper comparison would look like this:
Code:
if [ $t -gt 86400 ]

This is all code, before modification :

Code:
#!/bin/sh
 
for i in /opt/product/arsystem/test/    
do file "$i"  
    x=${i##*.}
    z=${perl -e 'print time;}
    r=LicenseReport.txt.$x    
     t=$(echo $z-$x|bc)    
    if ((t>86400))
    then tar -cvf $r.tar $r
    
        echo $i;
         echo $z; 
         echo $x;
         echo $t; 
         echo $r;
    else
    fi
     done

Actually the error become : Syntax error line 19 unexpected end of file,
When I try to run the script in the command line it's work fine, after put in text file .sh everything goes wrong.
