A simpler portable way to do the same thing is:
It should work with any version of bash, ksh, or any other POSIX conforming shell.
The only portable option to the read utility is -r.
Note that I used printf instead of echo because the way you specify printing a prompt without a newline using echo varies from system to system.
Hi,
The gcc compiler has warned about using gets(), so I've been trying my hand at getline.
Problem is that I've been able to read from a file, but what I really need is to read from a user's input.
I want to use getline like a scanf() command, but I can't figure what to substitute for the fp... (6 Replies)

read -p "New user? " user
Is it possible to have it so if the user enters nothing and just presses return it can resort to a specified value instead?
Thanks! :) (5 Replies)

echo
ECHO(1) BSD General Commands Manual ECHO(1)NAME
echo -- write arguments to the standard output
SYNOPSIS
echo [-n] [string ...]
DESCRIPTION
The echo utility writes any specified operands, separated by single blank (' ') characters and followed by a newline ('
') character, to the
standard output.
The following option is available:
-n Do not print the trailing newline character. This may also be achieved by appending 'c' to the end of the string, as is done by iBCS2
compatible systems. Note that this option as well as the effect of 'c' are implementation-defined in IEEE Std 1003.1-2001
(``POSIX.1'') as amended by Cor. 1-2002. Applications aiming for maximum portability are strongly encouraged to use printf(1) to sup-
press the newline character.
Some shells may provide a builtin echo command which is similar or identical to this utility. Most notably, the builtin echo in sh(1) does
not accept the -n option. Consult the builtin(1) manual page.
EXIT STATUS
The echo utility exits 0 on success, and >0 if an error occurs.
SEE ALSO builtin(1), csh(1), printf(1), sh(1)STANDARDS
The echo utility conforms to IEEE Std 1003.1-2001 (``POSIX.1'') as amended by Cor. 1-2002.
