hey sorry, i wrote the description but don't lnow how it got erased.
i have a set of commands inside a text file. 1 command per line.
command.txt
Code:
echo "start"
ls -l
pwd
i want to execute these commands one by one and after finishing the last command, again it should start from the 1st command.
infinity.sh
Code:
count=0
while :
do
while read exe_command
do
(( count++ ));
echo "$exe_command"
result_$count=`$exe_command`
done < command.txt
echo ""
done
the commands are not getting executed.
output:
e
Code:
cho "start"
infinite.sh: line 8: result_178="start": command not found
ls -l
infinite.sh: line 8: result_179=total: command not found
pwd
infinite.sh: line 8: result_180=/home: No such file or directory
So, you are trying to set a variable variable name then. Have you considered using an array?
Code:
#!/bin/ksh93
set -A result
count=0
while :
do
while read exe_command
do
(( count++ ));
echo "$exe_command"
result[$count]=`$exe_command`
done < command.txt
echo ""
done
for i in 1 2 3 4 5
do
echo "Result for $i is ${result[$i]}"
done
Of course, this is assuming that you have a simple value to store in your variable. The output you have given us suggests that you want to store the output from ls -l in a variable. I'm not really sure that is a good thing to attempt.
Are you actually after storing the return code instead? In that case, change the line:-
Code:
result[$count]=`$exe_command`
to be:-
Code:
$exe_command
result[$count]=$?
There is also a limit to the number of items in the array, 0-1023 in ksh, 4 million in ksh93. Not sure on the bash limit.
WARNING - your logic is dangerous.
Imagine if someone could infect your input file and add any of the following:-
