The command chmod is used to
change file mode bits
The format of a symbolic mode is [ugoa...][[-+=][perms...]...], where
perms is either zero or more letters from the set rwxXst, or a single
letter from the set ugo. Multiple symbolic modes can be given, sepa‐
rated by commas.
(from the man or reference manual page for chmod).
The +x tells tells chmod to set the execute (or search for directories) flag on.
The $1 is usually used in scripts to mean the first parameter passed to the script. ($0 refers to the script itself) however if a shift has been executed, the parameters may have changed, so it's the first at the time of execution.
