16.3.5 Numeric tests
Numeric relational operators. The arguments must be entirely numeric
(possibly negative), or the special expression -l string
,
which evaluates to the length of string
.
- ‘
arg1 -eq arg2
’
‘arg1 -ne arg2
’
‘arg1 -lt arg2
’
‘arg1 -le arg2
’
‘arg1 -gt arg2
’
‘arg1 -ge arg2
’ These arithmetic binary operators return true if
arg1
is equal, not-equal, less-than, less-than-or-equal, greater-than, or greater-than-or-equal thanarg2
, respectively.
For example:
test -1 -gt -2 && echo yes ⇒ yes test -l abc -gt 1 && echo yes ⇒ yes test 0x100 -eq 1 error→ test: integer expression expected before -eq
