sh
Hangup
The shell received a hangupsignal. This signal typically arises when a
communication line is disconnected—for example, when a phone
connection is cut off.
In base#number: base must be in [2,36]
In a number of the form base#number, the value of the base was larger than
36 or less than 2. The only valid range for bases is from 2 through 36.
Invalid subscript
A shell array was indexed with a subscript that was outside the defined
bounds.
Illegal instruction
The shell received an illegal instruction signal. This signal typically occurs
when a process tries to execute something that is not a valid machine
instruction recognized by the hardware.
Misplaced subscript array name
The subscript for an array was missing or incorrect.
name is not an identifier
You attempted to use a non-alphanumeric name.
name: readonly variable
The given name is a read-only variable, and cannot be removed or
changed (see readonly).
name: no expansion of unset variable
The shell is operating with set –u, and you used an unset variable in a
substitution. For more information, see the set command.
No file descriptor available for redirection
When a file descriptor is redirected, the old value is remembered by the
shell by a duplication to yet another file descriptor. The total number of file
descriptors is limited by the system; hence, the shell may run out, even
though your command appears to be using far fewer than the maximum
number of descriptors.
Nested aliases
You have more than nine levels of aliases. For example:
alias a1=a2 a2=a3 a3=a4 ... a10=command
causes this error.
Pipe for coprocess
The shell cannot create a pipe for a coprocess. This may mean that your
session or the system as a whole has already set up its maximum number
of pipes.
...: restricted
If the shell has been invoked as a restricted shell, certain things are
disallowed—for example, the cd command, setting PATH, and output
redirection.
Temporary file error using here document
sh tried to create a temporary file holding the contents of a
