Compare the following two text files of the same format and write the differences (different records) into a text file.
Content of 1.txt：
Proto Local Address Foreign Address State
TCP 111.11.1.111:1975 221.181.70.12:5926 ESTABLISHED
Content of 2.txt：
Proto Local Address Foreign Address State
TCP 111.11.1.111:1975 221.181.70.12:5926 ESTABLISHED
TCP 111.11.1.111:1111 169.254.241.33:2222 ESTABLISHED
Content of result.txt with exported data will be:
Proto Local Address Foreign Address State
TCP 111.11.1.111:1111 169.254.241.33:2222 ESTABLISHED
esProc script for doing this：
| A | |
| 1 | E:\\test\\ |
| 2 | =fns.array().(file(A1+~).import@t().sort(#1,#2,#3,#4)) |
| 3 | =A2.merge@d(#1,#2,#3,#4)|A2.rvs().merge@d(#1,#2,#3,#4) |
| 4 | =file(A1+”result.txt”).export@t(A3) |
A1: The path where text files are stored
A2: fns is the script parameter for storing the two text files, 1.txt and 2.txt, under comparison. Import the files and sort each of them by all the fields
A3: The first half line of the code – A2.merge@d(#1,#2,#3,#4) – gets difference between 1.txt and 2.txt; the second half – A2.rvs().merge@d(#1,#2,#3,#4) – gets difference beweeen 2.txt and 1.txt. Results will then be merged.
A4: Export A3’s result to result.txt, which concludes the computation.
