Hi, You could try something like this... You may need to find a way to enable escape sequences in Your shell if it's not enabled by default. The trick here is to send BCKSPC with echo.
And You will have be wary of any other output produced by Your program, for example, if Your actions corresponding to sleep above actually writes stuff to stdout, You may want to redirect it temporarily to a file, which You can display after the loop is done.
When I run a third parties program from the command line (this program basically list's a whole load of stuff) and write the output to a file it splits the output, i.e. in the middle of the file appears the exit command.
If I don't redirect the output and write it to tty then the output is... (3 Replies)

What am I doing wrong? I was searching for the answer to assigning variables from output. I found this simple response
ls -l apply_want.m | read perms links owner group size mtime1 mtime2 mtime3 file
this should allow me to echo the variables
echo "$perms | $links | $owner | $group |... (2 Replies)
Hi, trying to store a comand involving a redirection in a variable and then run this variable. But the redirection gets lost.
Ex:
#!ksh
MYCMD="ls -l > dirlist.txt"
$MYCMD
This runs the command but displays the result in the terminal instead of redirecting it to the text file.
Can... (4 Replies)
Hi All,
How do I provide the output of a command to another command which is waiting for an input from the user ?
Ex : I need to login to a device via telnet. In the script, initially I use the "read" command to get the IP Address, Username and Password of the device from the user. Now,... (1 Reply)

Bit of a strange one.
Have a script called rapidclone_test.sh which calls Oracle rapidclone using su -c as an oracle osuser. However, if I control+c out to the calling shell anything entered is not displayed on the terminal. Any command executes successfully though.
Why is the standard... (1 Reply)

echo
echo(1B) SunOS/BSD Compatibility Package Commands echo(1B)NAME
echo - echo arguments to standard output
SYNOPSIS
/usr/ucb/echo [-n] [argument]
DESCRIPTION
echo writes its arguments, separated by BLANKs and terminated by a NEWLINE, to the standard output.
echo is useful for producing diagnostics in command files and for sending known data into a pipe, and for displaying the contents of envi-
ronment variables.
For example, you can use echo to determine how many subdirectories below the root directory (/) is your current directory, as follows:
o echo your current-working-directory's full pathname
o pipe the output through tr to translate the path's embedded slash-characters into space-characters
o pipe that output through wc -w for a count of the names in your path.
example% /usr/bin/echo "echo $PWD | tr '/' ' ' | wc -w"
See tr(1) and wc(1) for their functionality.
The shells csh(1), ksh(1), and sh(1), each have an echo built-in command, which, by default, will have precedence, and will be invoked if
the user calls echo without a full pathname. /usr/ucb/echo and csh's echo() have an -n option, but do not understand back-slashed escape
characters. sh's echo(), ksh's echo(), and /usr/bin/echo, on the other hand, understand the black-slashed escape characters, and ksh's
echo() also understands a as the audible bell character; however, these commands do not have an -n option.
OPTIONS -n Do not add the NEWLINE to the output.
