In this example, we want to make sure a certain file exists on the
|
|
remote server:
|
|
|
|
file=/tmp/file.log
|
|
ssh ${options} ${login} "if [ ! -e '$file' ] ; then touch '$file' ; fi"
|
|
|
|
Notice the command is surrounded by double quotes, and the \$file
|
|
variable is surrounded by single quotes. That has the effect to be
|
|
wordsplit-proof in the local shell (due to the double-quotes) and in the
|
|
remote shell (due to the single-quotes).
