Just manually copy /lib/terminfo/r/rxvt-unicode-256color to
$HOME/miniconda3/share/terminfo/r/, and also to
$HOME/miniconda3/envs/YOUR_ENVS_NAME/share/terminfo/r/.
将文档局部变量 fill-column 设置为一个非常大的值，例如 999999999 ，然后
revert-buffer ，然后在对应的段落 fill-paragraph ，即可。
可以直接使用 https://github.com/gdbinit/Gdbinit ，将其命名为 .gdbinit ，并且新建文件 .gdbinit.local 。文件 .gdbinit.local 中的配置将会覆盖 .gdbinit 中的配置。下面是我的配置：
set $SHOWCPUREGISTERS = 0
set $SHOW_CONTEXT = 0
set history size unlimited
set history remove-duplicates unlimited
# Cause GDB to print structures in an indented format with one member per line
set print pretty on通常来说这是无法办到的，参见 这个 issue 。然而，可以按照 这个回答 对 GDB 做下小改动，参见项目 gdb_fzf_patch 。
mkdir gdb-with-fzf
cd gdb-with-fzf
# clone
git clone https://github.com/filipkilibarda/gdb_fzf_patch
# download gdb
aria2c https://ftp.gnu.org/gnu/gdb/gdb-10.2.tar.xz
tar xvf gdb-10.2.tar.xz
cd gdb-10.2/
git init
git add .
git commit -m "first commit"
# apply the patch
git apply ../gdb_fzf_patch/gdb.patch
git add .
git commit -m "fzf patch"
# build gdb
mkdir build
cd build
../configure --with-python=$(which python) --enable-targets=all
make -j $(nproc)
sudo make install该问题来源于 https://stackoverflow.com/a/31804225 。
- 打开一个终端（该终端用于输出被调试程序的输出），执行
tty命令：
$ tty
/dev/pts/0- 打开另一个终端并进入
GDB，然后输入：
(gdb) tty /dev/pts/0
(gdb) runIf a program says
int *array = (int *) malloc (len * sizeof (int));you can print the contents of array with
(gdb) p *array@len以上来自 官方文档 ，但是在用 github.com/gdbinit/Gdbinit 这个配置时，需要注意 @ 后面的指针长度默认是十六进制，例如若我们想打印长度为 10 的数组，下面的代码：
(gdb) p *array @ 10会打印出 16 个元素。正确的代码应该是：
(gdb) p *array @ 0x10或者，
(gdb) p/d *array @ 10我发现一个大概是微软文档库中的一个很有用的表格， 无符号整型向其他类型的转换汇总：

首先可以使用 xinput list 查看设备名称:
⎡ Virtual core pointer id=2 [master pointer (3)]
⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)]
⎜ ↳ ELAN067B:00 04F3:31F8 Mouse id=9 [slave pointer (2)]
⎜ ↳ ELAN067B:00 04F3:31F8 Touchpad id=10 [slave pointer (2)]
⎜ ↳ TPPS/2 Elan TrackPoint id=14 [slave pointer (2)]
⎣ Virtual core keyboard id=3 [master keyboard (2)]
↳ Virtual core XTEST keyboard id=5 [slave keyboard (3)]
↳ Video Bus id=6 [slave keyboard (3)]
↳ Power Button id=7 [slave keyboard (3)]
↳ Sleep Button id=8 [slave keyboard (3)]
↳ Intel HID events id=12 [slave keyboard (3)]
↳ AT Translated Set 2 keyboard id=13 [slave keyboard (3)]
↳ ThinkPad Extra Buttons id=15 [slave keyboard (3)]
↳ sof-hda-dsp Headphone id=11 [slave keyboard (3)]然后：
xinput disable "ELAN067B:00 04F3:31F8 Touchpad"
xinput disable "TPPS/2 Elan TrackPoint"也可以将笔记本电脑的键盘关闭：
xinput float 13其中 13 是 AT Translated Set 2 keyboard 的 ID。
重新开启：
xinput reattach 13 3例如我想禁用无线网卡，则首先用 lspci | grep -i wifi 查询其 PCI 地址：
00:14.3 Network controller: Intel Corporation Alder Lake-P PCH CNVi WiFi (rev 01)然后编写 udev rules 文件：
ACTION=="add", KERNEL=="0000:00:14.3", SUBSYSTEM=="pci", RUN+="/bin/sh -c 'echo 1 > /sys/bus/pci/devices/0000:00:14.3/remove'"将其命名为 /etc/udev/rules.d/10-wireless-card.rules 即可。
