With bash:

while read line; do echo -e "$line\ntest"; done < filename

after:

awk '{print $0 "\ntest"}' file

before:

awk '{print "test\n" $0}' file

at end:

awk '{print $0 "test"}' file

at beginning:

awk '{print "test" $0}' file

ITYM:

while IFS= read -r line
do
echo "$line"
echo "TEST"
done < file

or even:

while IFS= read -r line
do
echo "$line\nTEST"
done < file

Ed.

printf '%s\n' "$line"

But running 2 commands per line is a very strange thing to do
especially when you can do the whole thing with only one
command.

Its a perfectly legit way to do it. For the record, why use a while
loop when awk can do it? is it strange? :)

No. In the part you snipped:

>>

>> done < file


he's using /bin/sh with echo so his shell may not support printf while he's
obviously happy with echo. So, while printf may work, it's not what I meant.

Sorry, I have been scripting in bourne shell since day one, although I
am learning bash now, old habits i guess. :). Last checked, my
Solaris box does have printf, so I guess it should work fine too.
cheers

printf is a standard Unix command so should be in those Unices
where /bin/sh is still a
non-standard/deprecated/old-fashioned/you-name-it Bourne shell.

On the contrary, "read -r" is not Bourne (except for that
anecdotic Unix v8/SVR4.2 version)

Just because printf exists doesn't mean you can't be happy using echo.

Good to know.

Sure, but you need to beware that echo is unreliable and
unportable. Especially, there's no guarantee of the behavior if
its arguments start with "-" or contain backslash characters.

So I think it's good practice to systematically replace it with
"printf" which doesn't have those issues.
