如何使用殼

Question

我已經數據如下

11111 22222 33333 44444      55555   66666 

我想的輸出數據通過轉換如下

11111,22222,3333,4444      ,55555   ,66666 

我使用tr命令試圖插入一個分隔符每隔第n列請在4444或55555之後使用逗號。注意：4444和5555之間有很多空格。是否可以用逗號填充第6,12,127,46等列的空格？

Answer 1

如果您的實際Input_file與顯示的樣本相同，那麼以下內容可能也會對您有所幫助。

awk '{gsub(/ [0-9]+/,",&");gsub(/, /,",")} 1' Input_file 

輸出如下。

11111,22222,33333,44444      ,55555   ,66666 

說明上面的命令：

awk '{ 
gsub(/ [0-9]+/,",&"); ##gsub is awk utility to substitute things, so its format is gsub(regex_for_strings_to_be_replaced,with_whom_it_should_be_replaced,variable/line). So here I am substituting globally space then all digits(continuous ones) with a comma and (matched regex itself, which is space then all digits(continuous ones)). 
gsub(/, /,",")  ##Using gsub again here to replace comma then space(,) with only comma(,), to get the output into same shape in which OP has asked, it will remove space between command and digits which was created in above command. 
} 
1      ##awk works on method of condition then action, so here I am making condition as TRUE by mentioning 1 and not mentioning any action so be default print action will happen, print of current line. 
' Input_file   ##Mentioning Input_file name here.

難道這只是做你正在尋找什麼？ （猜測中所需輸出的失蹤4人是一個錯字）

sed -E 's/ ([0-9])/,\1/g' data 

（使用-r而不是-E，如果你是在Mac）。
