The rules concerning the definition and use of aliases are somewhat
|
||||
confusing. BBaasshh always reads at least one complete line of input
|
||||
before executing any of the commands on that line. Aliases are
|
||||
expanded when a command is read, not when it is executed. Therefore,
|
||||
an alias definition appearing on the same line as another command does
|
||||
not take effect until the next line of input is read. The commands
|
||||
following the alias definition on that line are not affected by the new
|
||||
alias. This behavior is also an issue when functions are executed.
|
||||
Aliases are expanded when a function definition is read, not when the
|
||||
function is executed, because a function definition is itself a com-
|
||||
mand. As a consequence, aliases defined in a function are not avail-
|
||||
able until after that function is executed. To be safe, always put
|
||||
alias definitions on a separate line, and do not use aalliiaass in compound
|
