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.
Code:
#!/bin/sh
echo Started program...
echo -n "Progress: 00"
for x in $(seq -w 1 10); do # or some other loop condition
sleep 1 #Or some other useful code here...
echo -n "\b\b${x}"
done
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

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)

cat
cat(1) General Commands Manual cat(1)Name
cat - concatenate and print data
Syntax
cat [ -b ] [ -e ] [ -n ] [ -s ] [ -t ] [ -u ] [ -v ] file...
Description
The command reads each file in sequence and displays it on the standard output. Therefore, to display the file on the standard output you
type:
cat file
To concatenate two files and place the result on the third you type:
cat file1 file2 > file3
To concatenate two files and append them to a third you type:
cat file1 file2 >> file3
If no input file is given, or if a minus sign (-) is encountered as an argument, reads from the standard input file. Output is buffered in
1024-byte blocks unless the standard output is a terminal, in which case it is line buffered. The utility supports the processing of 8-bit
characters.
Options-b Ignores blank lines and precedes each output line with its line number.
-e Displays a dollar sign ($) at the end of each output line.
-n Precedes all output lines (including blank lines) with line numbers.
-s Squeezes adjacent blank lines from output and single spaces output.
-t Displays non-printing characters (including tabs) in output. In addition to those representations used with the -v option, all tab
characters are displayed as ^I.
-u Unbuffers output.
-v Displays non-printing characters (excluding tabs and newline) as the ^x. If the character is in the range octal 0177 to octal 0241,
it is displayed as M-x. The delete character (octal 0177) displays as ^?. For example, is displayed as ^X.
