Occasionally, I want to copy a short line of text to a remote computer. For instance, I have an URL for some real cool web site which, for whatever reason, I want to send to a remote host. I can always put the text in a file, and transfer it via scp.
$ cat > coolurl.txt http://really-cool-web-site/ $ scp coolurl.txt peter@192.168.1.112:
Or, you can use the following one-liner command:
$ echo 'http://really-cool-web-site/'|ssh peter@192.168.1.112 'cat >coolurl.txt'
The one-liner uses only simple commands such as echo, ssh and cat. It saves you the step of creating a new file on the local machine.
The text is saved to a file called coolurl.txt on the remote computer under your home directory.
Let me know your favourite way to accomplish the same thing.

I have this file on the remote host as ~/bin/log
#!/bin/bash -
LOGFILE="~/repo/log"
if [ "$1" ]; then
grep "$1" $LOGFILE
else
echo -n 'make entry '
read
case $REPLY in
'') cat $LOGFILE;;
*) echo $(date '+%F %T') $REPLY >> $LOGFILE;;
esac
fi
exit 0
Then, on each host I sit at, I have
alias log='ssh remote_host_address "bin/log"'
So if I don't enter any text, I get the file's contents
and if I do enter text it is time stamped and saved.
If I type log "searchterm" I get all the lines containing searchterm
P.S. Too bad code can't be offset to retain indentation
