When you start the terminal, the message -bash:[:missing`] appears.

The answer is written, so as a supplement,

[1-eq1]

This is an error.Because there is no space between 1 and ].
] should be written as a single argument.

The shell test command has an alias of c[] for its appearance.
When test is called "[", you must specify "]" at the end of the argument (just for appearance).

[1-eq1]

is

test1-eq1

It has the same meaning as , but omitting "]" as shown below results in a heading error.

[1-eq1]
# US>Error - >bash: [:missing`]'

If you encountered an error editing .bash_profile, you may have erased the "]" corresponding to "[" or put "[" where you shouldn't have put "

This is not a direct answer, but on the terminal,

$bash-l-x

If you run , you will be able to determine where the error occurs.For your information.
