Greetings to everybody. I would like to know if I can use the pipe and command tee to read from edited file and to write to him e.g. "sed '{s_A_B_}' file | tee file". :confused: I know it doesn't work with > but I don't know anything about it with tee. Thank you for your help. :) (1 Reply)

print -n "Input"
read input
export INPUT=$input

$COMMAND

The first one without "tee" works fine. echo "$INPUT" displays the values I type in for input. The second... (5 Replies)
Hi,
I have a script where i want to log in details to the standard output as well as log file so that its easy for tracing purposes.
I have used the "tee"command.
The problem with this is my scripts lines are getting longer as for each line i have

echo "hello world" |... (4 Replies)
Someone recently advised me to use the tee command to write to standard out.
Why would you pipe your commands to
tee -a <filename>
rather than just using
>> <filename>
?
For example:
date|tee -a myfile
seems to be the same as
date >> myfile
Is there a benefit to... (5 Replies)
Hi,
When I run the following command in terminal it works. The string TEST is appended to a file silently.
echo TEST | tee -a file.txt &>/dev/null
However, when I paste this same line to a file, say shell1.sh, and use bourne shell .
I run this file in terminal, ./shell1.sh.
However I... (1 Reply)
I have been using the command tee to store the output to a file and also write on the terminal. However I would need to put the program in the background although I would still need to see the file being updated like it was doing when using tee.
Any suggestions on how to look at the log file... (3 Replies)

That is, suppose it is retrieving this:

I'm on Ubuntu 14.04 and I manually updated my coreutils so that "tee" is now on version 8.27
I was running a script using bash where there is some write to pipe error at some point causing the tee command to exit abruptly while the script continues to run. The newer version of tee seems to prevent... (2 Replies)

scriptreplay
REPLAY(1) User Commands REPLAY(1)NAME
scriptreplay - play back typescripts, using timing information
SYNOPSIS
scriptreplay [options] [-t] timingfile [typescript [divisor]]
DESCRIPTION
This program replays a typescript, using timing information to ensure that output happens at the same speed as it originally appeared when
the script was recorded.
The replay simply displays the information again; the programs that were run when the typescript was being recorded are not run again.
Since the same information is simply being displayed, scriptreplay is only guaranteed to work properly if run on the same type of terminal
the typescript was recorded on. Otherwise, any escape characters in the typescript may be interpreted differently by the terminal to which
scriptreplay is sending its output.
The timing information is what script(1) outputs to standard error if it is run with the -t parameter.
By default, the typescript to display is assumed to be named "typescript", but other filenames may be specified, as the second parameter or
with option -s.
If the third parameter is specified, it is used as a speed-up multiplier. For example, a speed-up of 2 makes scriptreplay go twice as
fast, and a speed-up of 0.1 makes it go ten times slower than the original session.
OPTIONS
The first three options will overide old-style arguments.
-t, --timing file
File containing script timing output.
-s, --typescript file
File containing the script terminal output.
-d, --divisor number
Speed up the replay displaying this number of times. The argument is a floating point number. It's called divisor because it
divides the timings by this factor.
-V, --version
Display version information and exit.
-h, --help
Display a help message and exit.
EXAMPLE
% script -t 2> timingfile
Script started, file is typescript
% ls
<etc, etc>
% exit
Script done, file is typescript
% scriptreplay timingfile
