To refresh a single commit script, issue the refresh statement at the [edit system scripts commit file filename] hierarchy level:
[edit system scripts commit]
set file filename refresh;
[edit system scripts commit file filename]
source http://my.example.com/pub/scripts/iso.xsl;
If the commit script is written in XSLT, using the .xsl file extension is optional, but highly recommended. If the commit script is written in SLAX, the file must include the .slax file extension.
Once the statement has been issued, the router attempts to connect to the commit script source and retrieve the remote commit script file.
