Each nested use adds 5 levels to the template expansion depth, so 7 nested if-templates would use 35 levels (5*7) of the 41-level limit. Using P-if syntax: A similar if-structure can be coded without Template:If, by using the {} and {} templates in a "P-if" structure. Template:P1 always returns parameter 1, and P2 returns the 2nd. So, a ...
In Linux, if the script was executed by a regular user, the shell would attempt to execute the command rm -rf / as a regular user, and the command would fail. However, if the script was executed by the root user, then the command would likely succeed and the filesystem would be erased. It is recommended to use sudo on a per-command basis instead.

If the template has a separate documentation page (usually called "Template:template name/doc"), add [[Category:If-then-else templates]] to the <includeonly> section at the bottom of that page.
See also: the {{}} template. The #if function selects one of two alternatives based on the truth value of a test string. {{#if: test string | value if true | value if false}} As explained above, a string is considered true if it contains at least one non-whitespace character.

64-bit Hamilton C shell on a Windows 7 desktop. The C shell was extremely successful in introducing a large number of innovations including the history mechanism, aliases, tilde notation, interactive filename completion, an expression grammar built into the shell, and more, that have since been copied by other Unix shells.
