Not sure if this is possible, but I'm trying to read in a variable that needs to have its escape backslashes intact. So the person who enters the actual value does not have to type any \ characters. Example:
In this case the \ needs to be entered by the person who is prompted to enter input. Is there a way to preformat the read so that the \ can be inserted after the fifth character, and then a space created? Or does the person doing the input just have to remember to enter it each time?

Hi All,
I'll get a file whose 2nd line contains 3 fields: filename(variable length), file size char(10), and record count int(10). How do I cut it and put it into 3 variables?

I would like to make a script to read three variables (no fixed length or position) from a line and write them into a file, with fixed length and right-justified in each column. The fixed text (text1-text4) prior to the thee variables and the variables themselves are originally separated by spaces... (3 Replies)
If I set a variable within a while-read loop, sometimes it's local to the loop, sometimes it's global, depending on how the loop is set up. I'm testing this on a Debian Lenny system using both bash and dash with the same results.
For example:
# Pipe command into while-read loop

Heyas
Figured me had a 'typo' in tui-conf-set, i went to fix it.
Now, i also figured, it might be nice to have tui-conf-set report (to console, not only exit code) wether it could save the variable to the file or not.
This said, I appended this code: (the tui-title and tui-echo lines are... (3 Replies)

WRITE(1) BSD General Commands Manual WRITE(1)NAME
write -- send a message to another user
SYNOPSIS
write user [tty]
DESCRIPTION
The write utility allows you to communicate with other users, by copying lines from your terminal to theirs.
When you run the write command, the user you are writing to gets a message of the form:
Message from yourname@yourhost on yourtty at hh:mm ...
Any further lines you enter will be copied to the specified user's terminal. If the other user wants to reply, they must run write as well.
When you are done, type an end-of-file or interrupt character. The other user will see the message 'EOF' indicating that the conversation is
over.
You can prevent people (other than the super-user) from writing to you with the mesg(1) command.
If the user you want to write to is logged in on more than one terminal, you can specify which terminal to write to by specifying the termi-
nal name as the second operand to the write command. Alternatively, you can let write select one of the terminals - it will pick the one
with the shortest idle time. This is so that if the user is logged in at work and also dialed up from home, the message will go to the right
place.
The traditional protocol for writing to someone is that the string '-o', either at the end of a line or on a line by itself, means that it is
the other person's turn to talk. The string 'oo' means that the person believes the conversation to be over.
SEE ALSO mesg(1), talk(1), wall(1), who(1)HISTORY
A write command appeared in Version 1 AT&T UNIX.
BUGS
The sender's LC_CTYPE setting is used to determine which characters are safe to write to a terminal, not the receiver's (which write has no
way of knowing).
The write utility does not recognize multibyte characters.
