| - | ====== Shell Script ====== | ||
| - | ShellScript有多強大我不必贅述。我所撰寫的文章都是以前遇到問題所想到的解決方法，也許不是每個做法都很完美，畢竟都是遇到的東西越多，才越能學習到更多更精闢的語法。 | ||
| - | ===== Article List ===== | ||
| - | * [[.sell_script:sh_power_on_off_vm|如何透過Shellscript去開啟與關閉你的VM?]] | ||

| - | ===== 暫存區 ===== | ||
| - | ==== grep space ==== | ||
| - | 並非所有系統grep都支援\s去偵測空白，可以使用[:space:]或[:blank:]當替代方案。(實測SLES11 grep 2.5.1不支援\s寫法) | ||
| - | * [[http://unix.stackexchange.com/questions/81916/how-to-find-a-space-in-a-text-using-grep|how-to-find-a-space-in-a-text-using-grep?]] | ||
| - | * [[http://linux.vbird.org/linux_basic/0330regularex.php|鳥哥 - 正規表示法與文件格式化處理]] | ||
| - | ==== 確認行數 ==== | ||
| - | 代表有15行。 | ||
| - | <code bash> | ||
| - | > lspci | awk '{ print NR }' | ||
| - | 1 | ||
| - | 2 | ||
| - | .. | ||
| - | 15 | ||
| - | </code> | ||
| - | ==== Assign指令結果至變數 ==== | ||
| - | 使用`號去包起來，以下範例會顯示123。 | ||
| - | <code bash> | ||
| - | VAR=`echo 123` | ||
| - | echo $VAR | ||
| - | </code> | ||
| - | 假如指令有問題也要一併導至VAR，可以透過將stderr導向stdout: | ||
| - | <code bash> | ||
| - | VAR=`ff 2>&1` | ||
| - | echo $VAR | ||
| - | </code> | ||
