Subject: Sed in Script problem using expr
Hi All,
Can anyone help me with the following script problem please its driving me nuts.
myscript.sh:
NUM=`expr $i - 2`; printf %02d $NUM ; echo " "
-------------------------------
You need to save the output from the printf command:
NUM=`expr $1 - 2`
NUM=`printf %02d $NUM`
or, a one liner
NUM=`echo $i | awk '{printf "%02d", $1 - 2}'`
<<winmail.dat>>
