Hi,
if i got a file "foo.txt":
aaa
bbb
ddd
aaa

and i want to print the file out line-by-line,then how to do that ?
thanks a lot

...i mean in a script, if i want to read that file "foo.txt" and print out its contents line by line.
Thanks

I am assuming by "print" you mean "echo" ?? However, the rule would be the same for print -- see commented out line below.

The IFS sets the "input file seperator" which, by default, is space. What we're doing here is setting to be carriage return (ie. end of line). ^M means a physical ctrl-M (carriage return) -- in vi to do it use ctrl-V ctrl-M

#!/bin/ksh

IFS="^M"

for i in `cat foo.txt`
do
echo $i
# echo $i | lp
done
