Variables do not expand inside single quotes. Use double quotes.
However, I am concerned about your use of sed here. Are you running sed 100 times to read 100 lines?? That's like making 100 phone calls to say 100 words. It'd be much better to use read in a while loop:
read can even do input splitting, on spaces by default or other things controlled by the special IFS variable, which makes a lot of processing much simpler.
Hi there. If variables are named inside of a ksh script, how is it possible to pass these to sed?
The affected portion of my script goes something like this:
A=`cut -d. -f1 $FILE`
B=`cut -d. -f2 $FILE`
C=`cut -d. -f3 $FILE`
sed 's/1111/$A/g;s/2222/$B/g;s/3333/$C/g' file > anotherfile
