run script inside ksh shell script

Question

I am trying to execute a script ksh that reads a file and execute other script to access the MySQL database. But the second script doesn't return any result. Does anyone know why? please.

#!/bin/ksh

vet=($(cat lasts_tasks.txt))
echo ${vet[@]}

for workunit in ${vet[@]};
do
        echo "workunit:$workunit"
        exe="/var/www/boinc/m52cc/query_tasks.sh m52cc -workunitResult $workunit;"
        echo ""$exe
        result=`$exe`
        echo $result
done

The results are:

# ./lerArquivo.sh 
m52cc_job_5 m52cc_job_6 m52cc_job_7
workunit:m52cc_job_5
/var/www/boinc/m52cc/query_tasks.sh m52cc -workunitResult m52cc_job_5;

workunit:m52cc_job_6
/var/www/boinc/m52cc/query_tasks.sh m52cc -workunitResult m52cc_job_6;

workunit:m52cc_job_7
/var/www/boinc/m52cc/query_tasks.sh m52cc -workunitResult m52cc_job_7;

But when I execute the lines alone, I have the right result:

# /var/www/boinc/m52cc/query_tasks.sh m52cc -workunitResult m52cc_job_7;

Answer 1

The ; in your command is interpretted as a literal semicolon, so you're basically running

/var/www/boinc/m52cc/query_tasks.sh m52cc -workunitResult m52cc_job_6\; ;

Just remove the semicolon from your exe variable:

#!/bin/ksh

vet=($(cat lasts_tasks.txt))
echo ${vet[@]}

for workunit in ${vet[@]};
do
        echo "workunit:$workunit"
        exe="/var/www/boinc/m52cc/query_tasks.sh m52cc -workunitResult $workunit"
        echo ""$exe
        result=`$exe`
        echo $result
done
