How to compare the content inside a txt file?












-1















I have a txt file which named as output.txt:



output.txt

2128,4.4
2128,5.5


I wish to have a compare script that first line first number before comma is equal to second line first number, then it will return second line second number after comma.



output:
5.5


If the output.txt have different number for first line first number and second line first number, for example:



output.txt
2622,56
1011,65


Then expected output will be return a stringThe value is different

  • sed -e 's/^(.{4}).*/1/' out.txt but this will print out all line with first 4 integer

  • sed -e 's/,.*//' output.txt and this will print out all the line with the value before comma, I wish to just retrieve first line or second line so that i can make comparison, anyone can share ideas?

Confirmed in bash:



#!/bin/bash

file=/path/to/output.txt

if [[ $(awk -F , 'NR==1 {print $1}' $file) -eq $(awk -F , 'NR==2 {print $1}' $file) ]]; then

awk -F , 'NR==2 {print $2}' $text

else

echo "The value is different"

fi


-The variable file is assigned to the path of wherever output.txt is located.



-In the if statement, awk uses , as the delimiter and prints and compares the second values of the second column on each line.



-If the values are equal, then it prints the second column of the second line which is 5.5



-If the values are not equal, then it prints "The value is different".



I tested this with two files with the values that you specified. You can change the value of the file variable in the script to work with others.
