MacOS:修改 software limit

2019-12-092019-12-09 老王

今天小編要做壓力測試，用了在linux 常的工具 siege ,沒想到一打下去不是網站掛了，而是打不出去

[error] descriptor table full sock.c:133: Too many open files

1	[error] descriptor table full sock.c:133: Too many open files

在linux 不能難解, 下個ulimit -n xxxx 就好了, 所以我就下了

ulimit -n 65535
-bash: ulimit: open files: cannot modify limit: Operation not permitted

1 2	ulimit -n 65535 -bash: ulimit: open files: cannot modify limit: Operation not permitted

啊斯，我又要開始為難我自己..
參考這裡

sudo -s
vim /Library/LaunchDaemons/limit.maxfiles.plist
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
  <dict>
    <key>Label</key>
    <string>limit.maxfiles</string>
    <key>ProgramArguments</key>
    <array>
      <string>launchctl</string>
      <string>limit</string>
      <string>maxfiles</string>
      <string>65535</string>
      <string>65535</string>
    </array>
    <key>RunAtLoad</key>
    <true/>
    <key>ServiceIPC</key>
    <false/>
  </dict>
</plist>

#重下
ulimit -n 65535
#檢查
ulimit -a

sudo -s

vim /Library/LaunchDaemons/limit.maxfiles.plist

<?xml version="1.0" encoding="UTF-8"?>

<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">

<dict>

<key>Label</key>

<string>limit.maxfiles</string>

<key>ProgramArguments</key>

<array>

<string>launchctl</string>

<string>limit</string>

<string>maxfiles</string>

</array>

<key>RunAtLoad</key>

<true/>

<key>ServiceIPC</key>

</dict>

</plist>

#重下

ulimit -n 65535

#檢查

ulimit -a

打完收工，但這應該只有單次應用，永遠設定等我研究好再更新

MacOS-mkvtoolnix-mkv 編輯指令

2019-08-042019-08-04 老王

mkvtoolnix

mkvtoolnix 可以拿來做 mkv 簡單的併接，剪裁，字幕加減等等
缺點是在mac 上不支援GUI
安裝：

brew install mkvtoolnix

1	brew install mkvtoolnix

會產以下4個tool
mkvextract mkvinfo mkvmerge mkvpropedit
本次僅使用 add srt 的功能

mkvmerge -o out.mkv source.mkv sub.srt
or
mkvmerge -o out.mkv source.mkv –language 0:chi –track-name 0:zh_TW sub.srt

mkvmerge -o out.mkv source.mkv sub.srt

mkvmerge -o out.mkv source.mkv –language 0:chi –track-name 0:zh_TW sub.srt

languages 有iso , 可用以下指令查詢
mkvmerge –list-languages
4G 檔案走SMB，大概只花了不到5分鐘，蠻快的

mkvtoolnix
