I want to create some vars such as delay and size in ansible
delay: */5 * * * * root stat --printf="\%Y\t\%n\n" /pool/slow/backup/daily/* | sed -ne 's/^\([0-9]\+\)\t\(.*\)$/node_backup_delay{directory="\2"} \1/p' > /var/lib/node_exporter/textfile_collector/backup_delay.prom.$$ && mv /var/lib/node_exporter/textfile_collector/backup_delay.prom.$$ /var/lib/node_exporter/textfile_collector/backup_delay.prom
size: */5 * * * * root du -sb /pool/slow/backup/daily/* | sed -ne 's/^\([0-9]\+\)\t\(.*\)$/node_directory_size_bytes{directory="\2"} \1/p' > /var/lib/node_exporter/textfile_collector/directory_size.prom.$$ && mv /var/lib/node_exporter/textfile_collector/directory_size.prom.$$ /var/lib/node_exporter/textfile_collector/directory_size.prom
But when i start playbook i receive an error
PLAY [all] ***************************************************************************************************************************************************************************************************************************************************************
ERROR! Syntax Error while loading YAML.
did not find expected alphabetic or numeric character
The error appears to be in '/home/dude/gitlab.com/office-deploy/code/inventories/host_vars/main1/main.yml': line 1, column 9, but may
be elsewhere in the file depending on the exact syntax problem.
The offending line appears to be:
delay: */5 * * * * root stat --printf="\%Y\t\%n\n" /pool/slow/backup/daily/* | sed -ne 's/^\([0-9]\+\)\t\(.*\)$/node_backup_delay{directory="\2"} \1/p' > /var/lib/node_exporter/textfile_collector/backup_delay.prom.$$ && mv /var/lib/node_exporter/textfile_collector/backup_delay.prom.$$ /var/lib/node_exporter/textfile_collector/backup_delay.prom
^ here
We could be wrong, but this one looks like it might be an issue with
unbalanced quotes. If starting a value with a quote, make sure the
line ends with the same set of quotes. For instance this arbitrary
example:
foo: "bad" "wolf"
Could be written as:
foo: '"bad" "wolf"'
Can anyone say to me which quotes i should use?
I use '''...''', ' "..." ' and nothing work
According your description of the syntax problem and the comment about YAML multiline strings, I've created a small test with Block Scalar Style: folded and Block Chomping: strip

Please take note that using delay would result into a
[WARNING]: Found variable using reserved name: delay
Maybe another approach for you could be Templating or concatenate variable strings.
