Shell-Script
不使用“column - t”均勻對齊列
我有一個從 Korn shell 腳本創建的輸出文件。我需要將輸出與空格均勻對齊。不幸
column -t的是，在 AIX 上不可用。實際文件：

awk腳本期望讀取同一個文件兩次。第一次，它記錄輸入數據中每列的最大寬度。第二次，它列印格式化為該最大寬度的列。如果
delim設置了變數，則使用它來分隔列，否則使用空格字元。預設情況下假定原始數據是空格分隔的。如果它是製表符分隔的，
-F '\t'請在命令行上使用。對給定數據進行兩次測試（注意輸入文件必須指定兩次）：

awk程序並採用兩個選項的 shell 腳本：
-d delim``delim要使用的輸出分隔符在哪裡。-D delim要使用的輸入分隔符在哪裡delim（例如-D '\t'輸入數據中的製表符）。該腳本將像這樣用於重新創建上面的兩個執行：
