回复 #18 blackold 的帖子
黑哥又拿小弟开涮?
lz标签就是个记号(黑哥说的"狗尿"),要注意的是
b label
Branch to label; if label is omitted, branch to end of script.
t label
If a s/// has done a successful substitution since the last input line was read and since the last t or T command, then branch to label; if label is omitted, branch to end of script.
T label
If no s/// has done a successful substitution since the last input line was read and since the last t or T command, then branch to label; if label is omitted, branch to end of script.
b、t和T的共同点是“if label is omitted, branch to end of script”
不同点是b无条件跳转,t和T有条件跳转 |
