是否可以在GDB中为命令定义任意组合键?我想知道是否有类似VIM map命令的东西。例如,我想映射到下一步,步骤等等..

GDB使用GNU readline来读取输入。文档here(或只需键入man readline
)。
特别要注意如何绑定F1以插入文本Function key 1
。

映射gdb中的密钥(在gdb / cygwin / win7上测试)
1. Start gdb
2. Find the key generated by F7, Press C-v F7
(gdb) ^[[18~
3. vi ~/.inputrc
# Map F7 to next
"\e[18~": "n\n"
4. Restart gdb, and now F7 will be mapped to "next\n"

# Sample ~/.inputrc
$if Gdb
"\e[23~": "next\n # [F7] next.\n"
"\e[A": "# Up key\n"
"\e[B": "next\n # [Down] next line.\n"
"\e[C": "step\n # [Right] step into func.\n"
"\e[D": "finish\n # [Left] to finish.\n"
$endif
gdb内置基于文本的gui称为TUI模式,甚至适用于cygwin / win7,样例用法:
> g++ -Wall -g -lm -std=c++14 hello.cpp
> gdb -tui a.exe
按C-x s ..进行单键模式
q - quit, exit SingleKey mode.
c - continue
d - down
f - finish
n - next
r - run
s - step
u - up
v - info locals
w - where
