awk string removal
Hi,

I am trying to remove a string ".var" using the below command but it's not working as expected, when I execute this in the command prompt using the echo it's working fine , please let me know where I am doing it wrong.

Code:
UYRD=$FILE_$timestamp.csv | awk '{gsub(".var", "");print}' # this is not giving any output

echo /root/src/.var | awk '{gsub(".var", "");print}' #when I tested in command prompt it is working fine

Regards,
Shruthi

Why should it give any output, as there's no input?

EDIT: Try
Code:
UYRD=$(echo $FILE_$timestamp.csv | awk '{gsub(".var", "");print}')

or, you could do it with shell parameter expansion, here: pattern substitution:
Code:
UYRD=${FILE_$timestamp.csv/.var}

Thanks for the quick reply.

I tried the first command I am getting the '<' unexpected. And the second command is giving bad substitution error,

timestamp=`date '+%Y%m%d%H%M%S'`
FILE=/root/cdr/src.var.csv

Sorry, my fault. Make it
Code:
UYRD=${FILE_/.var}$timestamp.csv

FILE and FILE_ are two different things.

And, use code tags!

Try:
Code:
UYRD="$(echo $FILE | awk '{gsub(".var","")}1')_${timestamp}.csv"
