Bash Script error?

Shell Programming and Scripting
1

I'm currently playing with the below script;

#!/bin/sh
for d in  /export/home/siward/staff/pasit/jamiecr/scripts/first-file.sh \
             /export/home/siward/staff/pasit/jamiecr/scripts/second-file.sh \
             /export/home/siward/staff/pasit/jamiecr/scripts/third-file.sh \
             /export/home/siward/staff/pasit/jamiecr/scripts/fourth-file.sh
do
     $d
     RC=$?
     if test "$RC" != "0"
     then
          echo "Do you wish to continue? [y]/n"
     read N
     case "$N" in
        Y* | y* )
              ;;
        * )
              exit $RC
              ;;
      esac
fi
done

Once it has processed /export/home/siward/staff/pasit/jamiecr/scripts/first-file.sh the below error appears;

-bash-3.00$ ./DB_gen.sh
./DB_gen.sh: /export/home/siward/staff/pasit/jamiecr/scripts/second-file.sh: cannot execute
Do you wish to continue? [y]/n

All the scripts look like this;

#!/bin/sh
cat <<EOD_CAT > second_gen_file
Actim Test Script
Second Generated File
EOD_CAT

Obviously changing for First, Third and Fourth.

Can anyone advise?

Cheers
Jamie

Do you have the execute permission to run '/export/home/siward/staff/pasit/jamiecr/scripts/second-file.sh' ?

You haven't execute permission on the file.
Two solutions :
1) Modify permissions of the file :
chmod +rx /export/home/siward/staff/pasit/jamiecr/scripts/second-file.sh

2) Modify script :

do
     /bin/sh $d
     RC=$?

No, however I have just amended the current chmod variables and it's working fine now!

Forgive me if this sounds daft, as I have said I'm still a newbie!

What does modifying the script the below do?

do
     /bin/sh $d
     RC=$?

Also some of the scripts which are being run within this script are require a date stamp. Manually these would be run as;

./first-file.sh 04/10/2007

However when running the script I would need to replicate this. How could I make the script ask for user input for the date? So the script automatically adds the date (which the user inputs) onto the end of the above line

Cheers

#!/bin/sh
#
# User Input Date
#
if [ $1  ]
then
 
    echo using date provided $1
    ENDDATE="$1"
 
else
 
    d=`date +%d`
    m=`date +%m`
    y=`date +%Y`
 
    echo no date provided, defaulting to today $d/$m/$y
    ENDDATE="$d/$m/$y"
 
fi
#
# Begin Scripts

             /export/home/siward/staff/pasit/jamiecr/scripts/third-file.sh \
             /export/home/siward/staff/pasit/jamiecr/scripts/fourth-file.sh

do
     /bin/sh $d
     RC=$?
     if test "$RC" != "0"
     then
          echo "Do you wish to continue? [y]/n"
     read N
     case "$N" in
        Y* | y* )
              ;;
        * )
              exit $RC
              ;;
      esac
fi
done

How does this look? How can I tell the script to run the date at the end of specific sub-scripts?

7 
ENDDATE=`date +%d/%m/%Y`
8

Like so?

    echo no date provided, defaulting to today $d/$m/$y
    ENDDATE=`date +%d/%m/%Y`
9

that's right

Thanks for the reply. Can you tell me how I can apply the date to the end of specific scripts within this one?

E.G I need first-file.sh and thrid-file.sh to run as

./first-file.sh 04/10/2007
./third-file.sh 04/10/2007

But within the new script

Thanks again
Jamie

#!/bin/sh
    ENDDATE=date +%d/%m/%Y`

             /export/home/siward/staff/pasit/jamiecr/scripts/third-file.sh \
             /export/home/siward/staff/pasit/jamiecr/scripts/fourth-file.sh
do
    .....................
    .....................
    .....................
    "${d}" "${ENDDATE}"
    .....................
    .....................
    .....................

done

Thanks vgersh! Will this not effect all of the scripts?

13

It the other scripts ignore the command line arguments then all will be well, if not you can use a case statement

case `basename $d` in
    first-file.sh | third-file.sh )
             "${d}" "${ENDDATE}"
             ;;
    * )
             "${d}"
            ;;
esac

Looking something a little bit like;

#
# Begin Scripts
#
for d in  /export/home/siward/staff/pasit/jamiecr/scripts/first-file.sh \
             /export/home/siward/staff/pasit/jamiecr/scripts/second-file.sh \
             /export/home/siward/staff/pasit/jamiecr/scripts/third-file.sh \
             /export/home/siward/staff/pasit/jamiecr/scripts/fourth-file.sh
#
# Date dependant scripts
#
case `basename $d` in
    first-file.sh | thrid-file.sh )
             "${d}" "${ENDDATE}"
             ;;
    * )
             "${d}"
            ;;
esac
#
# Error Fail Safe
#

Thanks for your help guys, appreciated!
