Scrpiting

[Anoop P_2]

When we execute two commands in a single script and append the output in to a single file, the output comes like this:

#script.sh
Command1 >> output
Command2 >> output

# cat output
output of command1
output of command2

But if I want it this way:

output of command1 output of command2

how should I write the script 'script.sh'?

Apperciate immediate help!

Command1 >> output_1
Command2 >> output_2

paste output_1 output_2 >> final_output.
Man paste for details.

If you have complete control of command1 and command2 and they are only writing a single line each you can do it.

Assuming that command1 is using "echo" to output it's data then use a "\c" to stop the output of the carriage return e.g

echo "here is the data\c"

And command2 can just do an echo normally.

Hi

If output is doable

echo $(Command1)$(Command2) >> output

I'm not sure what you're asking. If you want the output of both commands on the same line, this is easy.

echo "result of command1 \c">>file
echo "result of command2">>file

The \c in the first echo statement suppresses the carriage return that echo normally appends. The second command gets the carriage return.

btw... do you want a space between the lines?

you could join the lines after the fact with and editor or awk. For examples:

echo "1,2 j\nw" | ed x

The usage advantage of an editor is that you don't have to deal with an intermediate file.

With intermediate file and with space:

Command1 >> tmp
tr "[\012]" "[ ]" output
Command2 >> output

Without space:

Command1 >> tmp
tr -d "[\012]" output
Command2 >> output

Or you could fix the problem after the fact:

fix up output with perl with space:

perl -e '$_ = <>; chop; print $_ ." ".<>' output

fix up output with 'ed' without space:
echo "1,2 j\nw" | ed -s output

So many options!

Not sure what the intent is.

This method appends output of command1 to the bottom of command2
(
command1
command2 ) > output

If the output is multi line and you want them side by side. Paste works
command1 > output1
command2 > output2
paste output1 output2 > output

If you want the output side by side for comparision sdiff does a nice job of delimiting the changes.
command1 > output1
command2 > output2
sdiff output1 output2 > output

If the commands return one line of output and you want them side by side.
echo "$(command1)\c $(command2)" > output

Thank you for every one.

Infact I wanted it side by side to make a list of servers and their sendmail versions, to be created through a script.

Paste has worked well.

You could also use "pr -m output1 output2". Do a "man pr" to see other options available to help format the output.
