When running if condition, getting the following error
Hi All,
My input file name is 1.sh
the contents of file are
cat status2.txt | while read filename
do
echo "$filename"
echo "first content of the file is ${filename[0]}"
echo "second content of the file is ${filename[0]}"
echo "second content of the file is ${filename[0]}"
if [ ${filename[0]} -eq 0 -a ${filename[1]} -eq 0 -a ${filename[2]} -eq 0 ]
then
echo "please execute the step 1, then step 2 and then step3"
elif [ ${filename[0]} -eq 0 ]
then
echo "please execute the step 2 and then step3"
elif [ ${filename[0]} -eq 0 -a ${filename[1]} -eq 0 -a ${filename[2]} -ne 0 ]
then
echo "please execute the last step3"
fi
done
Where status2.txt contains the following contents 0 --> first content is 0
0 --> Second content is 0
--> Third content is the space
Now running the 1.sh file i am getting the following output.
0
first content of the file is 0
second content of the file is 0
second content of the file is 0
./1.sh: [: too many arguments -------> Error
please execute the step 2 and then step3
0
first content of the file is 0
second content of the file is 0
second content of the file is 0
./1.sh: [: too many arguments -------> Error
please execute the step 2 and then step3
first content of the file is
second content of the file is
second content of the file is
./1.sh: [: too many arguments -------> Error

can anybody tell me that why i am getting the above error??
It is very urgent, Please response me ASAP.
Presumably ${filename[0]} gets expanded into an empty string, and test isn't able to parse that. Remember that unquoted empty strings will simply disappear. Either quote the strings, or append a character before them (or, to be on the safe side, do both -- that's why you frequently see something like if [ X"$string" = X ])
I don't understand why you expect $filename to turn into an array. Your while loop reads one line at a time, and the value you read replaces the previous value for $filename. If you want it to be an array, you need to initialize it in a different way.
Maybe you really mean something like this.
This will still print an error message if not all the input is numeric (that's the "integer expression expected" case in the example above). You might be better off using a case statement instead; it's much less sensitive to the type of input etc than test (aka "[").

I have two scripts:
SCR1 which takes between 5 seconds to 15 minutes and needs to be run every 23 minutes.
SCR2 which needs to be run every 5 minutes but only if SCR1 is not running at that moment.
How can I do this task?
Best Regards
