cli tricks
1.0.0
في كثير من الأحيان في عملنا اليومي ، نواجه الحاجة إلى تشغيل الأشياء في CLI - وغالبًا ما يثبت هذا أنه أصعب مما يتوقعه المرء. بروح توفير الوقت للآخرين ، قررنا تجميع قائمة من تلك التي وجدنا أنها مفيدة وغير واضحة.

.* <-- this means match zero or more characters
[ <-- this means match a literal [ character
( <-- this starts saving the pattern for later use
[^]]* <-- this means match any character that is not a [ character
the outer [ and ] signify that this is a character class
having the ^ character as the first character in the class means "not"
) <-- this closes the saving of the pattern match for later use
] <-- this means match a literal ] character
/1 <-- this means replace everything matched with the first saved pattern
(the match between "(" and ")" )
/g <-- this means the substitution is global (all occurrences on the line)
