bash - Shell equality operators (=, ==, -eq) - Stack Overflow 530 = and == are for string comparisons -eq is for numeric comparisons -eq is in the same family as -lt, -le, -gt, -ge, and -ne == is specific to bash (not present in sh (Bourne shell), ) Using POSIX = is preferred for compatibility In bash the two are equivalent, and in sh = is the only one that will work
shell - How can I compare numbers in Bash? - Stack Overflow BTW, in bash a semi-colon is a statement separator, not a statement terminator, which is a new-line So if you only have one statement on a line then the ; at end-of-line are superfluous Not doing any harm, just a waste of keystrokes (unless you enjoy typing semi-colons)
html - What do lt; and gt; stand for? - Stack Overflow I know that the entities lt; and gt; are used for < and >, but I am curious what these names stand for Does lt; stand for something like "Left tag" or is it just a code?
