Help with a loop

I have 2 servers syncing some directories with an rsync script. They are in different countries. The rsync script is executed on Server#1. I am using 'fswatch' to execute the script automatically, when the directory is modified.

Here is where I am looking for help:

After 'fswatch' see's a directory change, it triggers my rsync script on Server#1. I need the rsync script to look at the Server#2 and check a file which contains the string "open" or "closed". If it says "closed", I want the rsync to script to execute. If it says "open", I don't want the rsync script to execute, but rather wait x seconds and check the file again (the file will eventually change to "closed", allowing the script to run).

Any insight on structuring this is greatly appreciated, I haven't figured out how to setup the loop of 'check file/don't execute/wait/check again' logic.

I think I found the logic. Can somebody tell me how to get this to time out after say 100 tries?

Code:
STATUSFILE=/Users/patrick/Desktop/temp/remoteserverstatus
until grep -q closed "$STATUSFILE"; do
echo ‘waiting for sever to finish’; sleep 3
done
echo ‘running script’

rsync_selinux(8)					rsync Selinux Policy documentation					  rsync_selinux(8)

NAME
rsync_selinux - Security Enhanced Linux Policy for the rsync daemon DESCRIPTION
Security-Enhanced Linux secures the rsync server via flexible mandatory access control. FILE_CONTEXTS SELinux requires files to have an extended attribute to define the file type. Policy governs the access daemons have to these files. If you want to share files using the rsync daemon, you must label the files and directories public_content_t. So if you created a special directory /var/rsync, you would need to label the directory with the chcon tool. chcon -t public_content_t /var/rsync To make this change permanent (survive a relabel), use the semanage command to add the change to file context configuration: semanage fcontext -a -t public_content_t "/var/rsync(/.*)?" This command adds the following entry to /etc/selinux/POLICYTYPE/contexts/files/file_contexts.local: /var/rsync(/.*)? system_u:object_r:publix_content_t:s0 Run the restorecon command to apply the changes: restorecon -R -v /var/rsync/ SHARING FILES
If you want to share files with multiple domains (Apache, FTP, rsync, Samba), you can set a file context of public_content_t and pub- lic_content_rw_t. These context allow any of the above domains to read the content. If you want a particular domain to write to the pub- lic_content_rw_t domain, you must set the appropriate boolean. allow_DOMAIN_anon_write. So for rsync you would execute: setsebool -P allow_rsync_anon_write=1 BOOLEANS
