But I'having problems to get the user selection because when I do the read to ask the user, the script reads the next line of the file.

I've discovered a very annoying problem in sh:
echo -en "one\ntwo\nthree" | while read VALUE
do
echo "${VALUE}"
done This will print one and two, but not three. The last line is IGNORED because it lacks a newline. This makes it hard to use sh for things like CGI scripting; you have... (6 Replies)

Hey, guys!
Trying to research this is such a pain since the read command itself is a common word. Try searching "unix OR linux read command examples" or using the command substitution keyword. :eek:
So, I wanted to use a command statement similar to the following.
This is kinda taken... (2 Replies)

ul
UL(1) General Commands Manual UL(1)NAME
ul - do underlining
SYNOPSIS
ul [ -i ] [ -t terminal ] [ name ... ]
DESCRIPTION
Ul reads the named files (or standard input if none are given) and translates occurrences of underscores to the sequence which indicates
underlining for the terminal in use, as specified by the environment variable TERM. The -t option overrides the terminal kind specified in
the environment. The file /etc/termcap is read to determine the appropriate sequences for underlining. If the terminal is incapable of
underlining, but is capable of a standout mode then that is used instead. If the terminal can overstrike, or handles underlining automati-
cally, ul degenerates to cat(1). If the terminal cannot underline, underlining is ignored.
The -i option causes ul to indicate underlining onto by a separate line containing appropriate dashes `-'; this is useful when you want to
look at the underlining which is present in an nroff output stream on a crt-terminal.
SEE ALSO man(1), nroff(1), colcrt(1)BUGS
Nroff usually outputs a series of backspaces and underlines intermixed with the text to indicate underlining. No attempt is made to opti-
mize the backward motion.
