Output of a Grep(Which already has a variable) into a Variabale
Hi All,
I have a an array, in which i need to loop through all the variable and check each variable individually for a pattern.

For ex
Code:
#!/bin/ksh

set -A FileNames $(</Temp/AllNames)
echo "Total array elements :" ${#FileNames[*]}

for i in ${FileNames[@]}
do
# if the "${i} | grep Last" returns true for this then i have #to do some manipulations
#Something like below
Temp = `${i} | grep Last` 
 
done

Use CODE TAGS

you should not use Temp = `${i} | grep Last`. that should be Temp=$(echo ${i} | grep Last)

I would have avoided those ` u use. Rather having an array created for the whole file, I would have done like

Code:
#!/bin/ksh

echo "Total elements : $(cat /Temp/AllNames | wc -l)"

while read i
do
# if the "${i} | grep Last" returns true for this then i have #to do some manipulations
#Something like below
Temp=$(echo ${i} | grep Last)
done < /Temp/AllNames

This would be simple than your code, 'cause it needs memory for allocation Smilie
