配置 命令 小技巧

Aliases 🔗

  • 快捷命令别名，将配置内容放置在~/.bash_aliases中，bash会自动加载。 
    alias df='df -h'
alias du='du -h -d 2'
alias ft='figlet -f digital'
alias ping='ping -n 10'
alias pstree='pstree -chpst'
alias tree='tree -L 2'

Inputrc 🔗

  • Bash输入时忽略大小写进行Tab补全，配置文件放置于~/.inputrc。 
    set completion-ignore-case on

Git configuration 🔗

  • git相关配置，配置文件放置于~/.gitconfig。 
    [user]
    name = User Name
    email = User E-mail
[color]
    ui = auto
[core]
    quotepath = false
    symlinks = true
[alias]
    bl = blame
    br = branch
    ci = commit
    cl = clone
    co = checkout
    df = diff
    dt = difftool
    ft = fetch
    lg = log --pretty=format:"%C(auto) %h | %ai | %an | %s%d" --graph
    pl = pull -v --progress
    ps = push -v --progress
    sm = submodule
    st = status
[filter "lfs"]
    clean = git-lfs clean -- %f
    smudge = git-lfs smudge -- %f
    process = git-lfs filter-process
    required = true

转换文件中的换行符 🔗

  • 使用perl命令替换文件中的换行符 
    perl -pi -e 's/\r\n|\n|\r/\r\n/g' file-to-convert  # Convert to DOS
perl -pi -e 's/\r\n|\n|\r/\n/g'   file-to-convert  # Convert to UNIX
  • 使用dos2unix命令完成替换

递归转换文件中的Tabs为Spaces 🔗

  • Install sponge

    sudo apt-get install moreutils  # Debian-like
brew install sponge             # macOS

  • The complete one-liner

    find ./ -iname '*.java' -type f -exec bash -c 'expand -t 4 "0" | sponge "0"' {} \;

  • Explanation

    ./              需要替换的文件夹
-iname          需要替换的文件名（文件名不区分大小写，例如*.java and .JAVA)
type -f         只替换文件（不包含文件夹，二进制文件，文件链接
-exec bash -c   在子Shell中为每个匹配的文件执行命令
expand -t 4     将Tab拓展为4个空格
sponge          接收来自expand的标准输入并写会同一个文件

  • Note

    • A simple file redirection (> “$0”) won’t work here because it would overwrite the file too soon.
    • Advantage: All original file permissions are retained and no intermediate tmp files are used.

从git仓库中删除文件或文件夹 🔗

不同于git rm删除文件后再提交一次记录，此方法将文件或文件夹从仓库中永久删除（包括本地.git存储库、工作区、以及remote）。

  • 删除文件或文件夹

    git filter-branch --force --index-filter 'git rm --cached -rf --ignore-unmatch /PATH/TO/RM' --prune-empty --tag-name-filter cat -- --all

  • 在本地永久删除

    rm -rf .git/refs/original/
git reflog expire --expire=now --all
git gc --prune=now
git gc --aggressive --prune=now

  • 推送到remote

    git push origin master:master --tags --force

  • 清理remote

    git remote prune origin

Windows 11右键菜单配置 🔗

  • 平铺

    reg add "HKCU\Software\Classes\CLSID{86ca1aa0-34aa-4e8b-a509-50c905bae2a2}\InprocServer32" /f /ve
taskkill /f /im explorer.exe & start explorer.exe

  • 折叠

    reg delete "HKCU\Software\Classes\CLSID{86ca1aa0-34aa-4e8b-a509-50c905bae2a2}" /f
taskkill /f /im explorer.exe & start explorer.exe

显示Windows照片查看器 🔗

将以下内容放置在reg文件中（例如、EnablePhotoViewer.reg）并运行。
