Append without Carriage Return

[TSch]

Hello everyone,

I understand that using >> I'm able to append lines to a file ...

Is it also possible to append words to the same line in the file somehow ?

e.g.:

hostname >> /file
cat /etc/hosts | grep 172 | awk '{ print $1 }' >> /file

This would generate let's say the following file content:

server
172.16.238.34

But I want it to look like this when I do a "cat /file":

server 172.16.238.34

Is it possible ?

Regards
Thomas

workaround: use command substitution, then finally echo one line into /file

[tt]name=$(hostname)
addr=$(grep 172 /etc/hosts)

echo "$name $addr" > /file[/tt]

Do you need the interemediate varaiables?

echo $(hostname) $(grep 172 /etc/hosts)

works for me.

Of course Columb, but I don't know what else Thomas wants to do with the strings, I assmume he just used this as a trivial example.

Other solution is to use printf or no-newline echo in the first instance

[tt]printf "%s " $(hostname) >> /file

grep whatever /etc/hosts >> /file[/tt]

or

[tt]echo "%s \c" $(hostname) >> /file

grep whatever /etc/hosts >> /file[/tt]
