Shell Programming and Scripting

Hi,

I'm writting a script to assign sm values to arrays and work on the values stored in array later. But i'm not able to work properly to use these arrays. intialising is one of the main problem as i'm not sure of array element count (they can increase/decrease). Copying the script. In case of any doubts please let me know.

count=0
total=`wc -l hk_mrm_jobs.txt`
echo $total
count=24
if [ $count -eq $total ]
then
echo $count
k=0
for j in `cat hk_mrm_jobs.txt`
do
fortime=`autorep -j $j | grep EQDEL | awk '{print $5}'` #getting a value from string and assign to array
myarray[$k] = $fortime
echo $k
k=`expr $k + 1`
done
fi
done

Please, use CODE tag when posting :

Code:

count=0
total=`wc -l hk_mrm_jobs.txt`
echo $total
count=24
if [ $count -eq $total ]
then
   echo $count
   k=0
   for j in `cat hk_mrm_jobs.txt`
   do
      fortime=`autorep -j $j | grep EQDEL | awk '{print $5}'` #getting a value from string and assign to array
      myarray[$k] = $fortime
      echo $k
      k=`expr $k + 1`
   done
fi
done

The last done statement is not associated with a while : Syntax error.
Are you sure that your input file contains 24 records ?

You for loop seems to be correct.
Another way to code this loop :

Code:

while read j
do
   myarray[${#myarray[*]}]=$(autorep -j $j | awk '/EQDEL/ {print $5}')
done < hk_mrm_jobs.txt

Code:

wc -l filename

returns o/p like this

Code:

rkumar@bdc4reteaix1w: /home/rkumar >wc -l restart_sshd.sh
       2 restart_sshd.sh

So, if you want only the count you should filter that out. Else, the subsequent if statement wont work. And,
There should not be spaces while assigning. It should be

Code:

myarray[$k]=$fortime

Thanks for the reply... Will take care to use code tag in future

But getting the error on running the script.. using While loop code


try.sh: syntax error at line 3: `myarray[${#myarray[*]}]=$' unexpected

The following syntax can be use (avoid the need of filtering output):

Code:

total=`wc -l < hk_mrm_jobs.txt`

Try to replace the $(...) by `...`

Code:

while read j
do
   myarray[${#myarray[*]}]=`autorep -j $j | awk '/EQDEL/ {print $5}'`
done < hk_mrm_jobs.txt
