xargs(eXtended ARGuments)是給指令傳遞參數的一個篩選器,也是組合多個指令的一個工具。 xargs 可以將管道或標準輸入(stdin)資料轉換成命令列參數,也能夠從檔案的輸出中讀取資料。 xargs 也可以將單行或多行文字輸入轉換為其他格式,例如多行變單行,單行變多行。 xargs 預設的指令是 echo,這表示透過管道傳遞給 xargs 的輸入將會包含換行和空白,不過透過

South Asian High | 南亞高壓

南亞高壓 (South Asian High) 南亞高壓是一種季節性的大氣系統,其形成主要與青藏高原在夏季的巨大熱源有關。 高原上空的空氣比周圍同高度的空氣更暖,導致高層大氣形成高壓,並引發空氣從高壓中心向四周流動,形成南亞高壓。 南亞高壓的成因: 青藏高原的熱力作用: 太陽輻射加熱:太陽輻射加熱青藏高原地表,使地表附近的空氣變暖。 陸地比海洋吸熱快,因此歐亞大陸夏季比周圍地區更熱,青藏高原作為

ecFlow | ECF_DATE is empty?

ecFlow -- Installation & Usage Key Points It seems likely that ECF_DATE is empty because the suite definition in ecFlow lacks a clock attribute, which is needed to generate the date. Research

Linux | Linux 權限詳解(chmod)

在Linux系統中,檔案權限受到嚴格控制,進行特定操作時必須擁有相應的權限才能成功執行。 Linux中的檔案權限類型主要包括讀取、寫入和執行,分別用字母 r、w、x 表示。 權限的層級分為擁有者、群組和其他用戶。每個檔案可以針對這三個層級設置不同的 rwx(讀寫執行)權限。通常,一個檔案只能屬於一個使用者和一個群組。如果其他使用者需要訪問該檔案的權限,可以將其加入擁有權限的群組,並且一個使用者
