Question

我有一个带有以下这些行的文本文件（A.txt）：

operator()

和其他文本文件（B.txt）一起使用以下这些行：

Aaaaaaa1
Aaaaaaa2
Aaaaaaa3

我想以这种方式将A.txt和B.txt结合在其他文件（OUTCOME.txt）中：

Bbbbbbb1
Bbbbbbb2
Bbbbbbb3

如何使用读取，grep，echo等在Linux中使用bash shell进行此操作？

Answer 1

只需paste即可：

$ cat file1
Aaaaaaa1
Aaaaaaa2
Aaaaaaa3

$ cat file2
Bbbbbbb1
Bbbbbbb2
Bbbbbbb3


$ paste -d $'\n' file1 file2
Aaaaaaa1
Bbbbbbb1
Aaaaaaa2
Bbbbbbb2
Aaaaaaa3
Bbbbbbb3

Answer 2

使用GNU sed：

sed 'R b.txt' a.txt > OUTCOME.txt

输出到OUTCOME.txt：

Aaaaaaa1
Bbbbbbb1
Aaaaaaa2
Bbbbbbb2
Aaaaaaa3
Bbbbbbb3

Answer 3

使用import tkinter as tk root = tk.Tk() # Change the original tkinter icon root.iconbitmap('C:\\Users\\bmxfi\Downloads\images.ico') # Set the title of the window root.title('Calculator') # Change the geometry of the window root.geometry('300x450+750+150') # Setting Minimum and Maximum window width and height root.minsize(width=300, height=450) root.maxsize(width=300, height=450) # Create Rows and Columns to display widgets root.rowconfigure(0, weight=100) root.rowconfigure(1, weight=100) root.rowconfigure(2, weight=100) # Columns start here: root.columnconfigure(0, weight=100) root.columnconfigure(1, weight=100) root.columnconfigure(2, weight=100) # Configuring the Main window named: root root.configure(bg='#353535') # Creating the main label that will display the calculated results lab_1 = tk.Label(root, width=40) lab_1.grid(row=0, column=1, columnspan=1, sticky='we') lab_1.configure(bg='#545454', font=('Computer Modern', 25, 'bold'), fg='White', justify='right') # Main Calculator Layout # List Box for a calculator layout box_1 = tk.Listbox(root) box_1.grid(row=1, column=1, rowspan=2) box_1.configure(bg='#353535', relief='flat') # Button Layout calculator_layout = [[(7, 1), (8, 1), (9, 1), ('(', 1), (')', 1)], [(4, 1), (5, 1), (6, 1), ('×', 1), ('÷', 1)], [(1, 1), (2, 1), (3, 1), ('+', 1), ('-', 1)], [(0, 1), ('±', 1), ('.', 1), ('-', 1), ('=', 1)]] # Iterating through my list to get a set of buttons row = 0 for i in calculator_layout: col = 0 for a in i: key_press = tk.Button(box_1, text=a[0]) key_press.grid(row=row, column=col, ipadx=10, ipady=8, sticky='we') key_press.configure(background='#545454', fg='white', font=('Computer Modern', 10), activebackground='red', state='normal') col += a[1] row += 1 root.mainloop()和echo：

read

第二个while IFS= read -r line1 && IFS= read -ru3 line2; do echo "$line1" echo "$line2" done < file1 3< file2使用不同的文件描述符（在这种情况下为read）非常重要。
