missing out on man web pages of some commands
man alias offers me
No guidebook access for pen names
The very same point goes with
export and also
eval. In the beginning I assumed it just takes place to shell integrated commands yet
man echo offers me the man web page.
With the exception of googling, exists a manner in which I can watch the documentation of those commands? Otherwise, exists a means to "install" those missing out on man web pages?
You possibly have the man web page for
echo due to the fact that the majority of systems have an
echo binary in
/bin, despite the fact that the majority of coverings give a constructed - in anyhow ; you're seeing the man web page for that binary. The man web pages for all the various other commands you're missing out on remain in the POSIX Programmer's Manual (man area 1P). Just how to install it will certainly rely on your distro ; on Gentoo they're in the
export, and also
eval are all component of
man builtin on Mac OS X and also, I think, on various other BSD systems.
On OS X, the man web pages for the builtin commands are all aliased to builtin, so if I type
man alias it will certainly bring up
man builtin. The trouble though is that
man builtin does not actually give details on the specific commands. Consequently, to get details on pen names, you need to make use of
While I favor reviewing man web pages from an incurable punctual, if missing out on from a system, I'll most likely to http://man.cx/ as it's rather thorough.
Builtin commands can be conveniently located by examining the man web page of your existing shell :
In the man web page of celebration, you'll locate :
alias [-p] [name[=value] ...] Alias with no arguments or with the -p option prints the list of aliases in the form alias name=value on standard output. When arguments are supplied, an alias is defined for each name whose value is given. A trailing space in value causes the next word to be checked for alias substitution when the alias is expanded. For each name in the argument list for which no value is supplied, the name and value of the alias is printed. Alias returns true unless a name is given for which no alias has been defined.
When doubtful, run
which alias when it reports builtin, or it can not be located in
$PATH, there's a great chance it's a builtin, so examine the ideal man web pages.
