john willow:/home/john mary willow:/home/mary joe willow:/home/joe able pine:/export/able baker peach:/export/baker
You can use the ampersand character (&) to substitute the key wherever the key appears. If you use the ampersand, the previous map changes to the following:
john willow:/home/& mary willow:/home/& joe willow:/home/& able pine:/export/& baker peach:/export/&
You could also use key substitutions in a direct map, in situations such as the following:
You can also simplify the entry further as follows:
Notice that the ampersand substitution uses the whole key string. Therefore, if the key in a direct map starts with a / (as it should), the slash is included in the substitution. Consequently, for example, you could not do the following:
Each ampersand is substituted by the value of any given key. Autofs interprets the asterisk as an end-of-file character.
If you have a map entry that contains special characters, you might have to mount directories that have names that confuse the autofs map parser. The autofs parser is sensitive to names that contain colons, commas, and spaces, for example. These names should be enclosed in double-quotes, as in the following:
/vms -ro vmsserver: - - - "rc0:dk1 - " /mac -ro gator:/ - "Mr Disk - "
