徹底清除停止點：
(gdb) info break
num type disp enb address what
1 breakpoint keep y 0x00005555555548dc in main at strcopy.c:46
stop only if i=10
breakpoint already hit 1 time
2 breakpoint keep y 0x00005555555548dc in main at strcopy.c:47
stop only if i==10
breakpoint already hit 1 time
3 breakpoint keep y 0x00005555555547f9 in mystrcopy2
at strcopy.c:30
stop only if p=="string copy"
4 breakpoint keep n 0x00005555555547ce in mystrcopy2
at strcopy.c:28
stop only if s2=="string copy"
5 hw watchpoint keep y i
breakpoint already hit 1 time
6 read watchpoint keep y i
7 acc watchpoint keep y i
breakpoint already hit 1 time
(gdb) delet breakpoint 1-2
(gdb) info break
num type disp enb address what
3 breakpoint keep y 0x00005555555547f9 in mystrcopy2
at strcopy.c:30
stop only if p=="string copy"
4 breakpoint keep n 0x00005555555547ce in mystrcopy2
at strcopy.c:28
stop only if s2=="string copy"
5 hw watchpoint keep y i
breakpoint already hit 1 time
6 read watchpoint keep y i
7 acc watchpoint keep y i
breakpoint already hit 1 time
禁止斷點4
(gdb) disable breakpoints 4
使能斷點4
(gdb) enable breakpoints 4
(gdb) info break
num type disp enb address what
3 breakpoint keep y 0x00005555555547f9 in mystrcopy2
at strcopy.c:30
stop only if p=="string copy"
4 breakpoint keep y 0x00005555555547ce in mystrcopy2
at strcopy.c:28
stop only if s2=="string copy"
(gdb) disable breakpoints 4
(gdb) info break
num type disp enb address what
3 breakpoint keep y 0x00005555555547f9 in mystrcopy2
at strcopy.c:30
stop only if p=="string copy"
4 breakpoint keep n 0x00005555555547ce in mystrcopy2
at strcopy.c:28
stop only if s2=="string copy"
用一次就停止斷點4
(gdb) enable breakpoints once 4
用一次就停止斷點3-4
(gdb) enable breakpoints once 3-4
用一次就刪除斷點4
(gdb) enable breakpoints delete 4
用一次就刪除斷點3-4
(gdb) enable breakpoints delete 3-4
成功解決 docker 清除所有已停止容器
docker rm docker ps a grep exited awk docker rm yyy zzz docker 刪除容器 yyy，zzz，這個可以連續寫 docker ps a 這個是輸出所有的容器 grep exited 將行中帶有exited的所有行輸出 awk 將每一行的第乙個短...
gdb積累學習
gdb積累學習 1 檢視當前檔案 通過gdb進行除錯的時候，有的時候因為跳轉的太多，所以不知道已經執行到了哪乙個檔案，這個時候，如果我們想看一下當前檔案的名字，可以使用下面的命令 gdb info source current source file is cdbstatement.cpp comp...
gdb除錯學習
一般來說，gdb主要幫忙你完成下面四個方面的功能 1 啟動你的程式，可以按照你的自定義的要求隨心所欲的執行程式。2 可讓被除錯的程式在你所指定的調置的斷點處停住。斷點可以是條件表示式 3 當程式被停住時，可以檢查此時你的程式中所發生的事。4 動態的改變你程式的執行環境。除錯的程式如下 root lo...
