DIFFLOTID,0001

I need to get the 0001 placed into a variable.

Hi Fernando,

If there are only two fields are seperated by comma, then you can use 'while'

oIFS=$IFS
IFS=","

while read first next
do

done < your_file
IFS=$oIFS

In the above, 'next' is your variable. The above won't work if there is are multiple commands in each line.

Im trying out to use the command below:

VAR=$(grep "DIFFLOTID" $FILE |awk -F \" '{print $1}')

but i get the whole string DIFFLOTID,0001

Hi,

Use this

VAR=$(awk -F "," '/DIFFLOTID/ {print $2}' your_file)

If there are more than one line containing DIFFLOTID, then VAR will have more than one value.

Hi SRI,

Thanks for your reply. It was a great help to a neophyte like me. I would like to ask now how can i know if the $var contains pure strings of numbers or alphanumerics?

Many thanks!
