Percent-signs (%) in the command, unless escaped with backslash \, will be changed into newline characters, and all data after the first % will be sent to the command as standard input.

Well a bunch of tests fail because GitHub is unstable and cloning repositories fail. Could someone with permissions on this project restart the Travis jobs for me? |

Well, I forced Travis to run again, sorry for closing/reopening but that was the only solution I had. This seems ready for review :) |

Using Debian's default shell for cron (
/bin/sh), the xtrabackup incremental cron was failing for me with an error message like:This is caused by percent-signs (
%) not being escaped. With/bin/sh, percent-signs (%) in the command, unless escaped with backslash , will be changed into newline characters, and all data after the first % will be sent to the command as standard input. Thus the EOF error.I also made another small commit to convert backtiks (`) into $(), which is the prefered POSIX way. https://pubs.opengroup.org/onlinepubs/9699919799/xrat/V4_xcu_chap02.html#tag_23_02_06_03 has a good writeup on it.
Happy to make modifications if required.
