我需要測試是否設(shè)置了變量。我已經(jīng)嘗試了幾種技術(shù)，但他們忽視了，只要%1用雙引號包圍時(shí)，如情況%1是"c:\some path with spaces"。IF NOT %1 GOTO MyLabel // This is invalid syntaxIF "%1" == "" GOTO MyLabel // Works unless %1 has double quotes which fatally kills bat executionIF %1 == GOTO MyLabel // Gives an unexpected GOTO error.根據(jù)本站點(diǎn)的介紹，這些是受支持的IF語法類型。因此，我沒有找到一種方法。IF [NOT] ERRORLEVEL number commandIF [NOT] string1==string2 commandIF [NOT] EXIST filename command
