What is the method for merging files in Linux?

There are several commonly used methods for merging files in a Linux system.

1. By using the cat command, you can combine multiple files into one file. For example, to merge file1.txt and file2.txt files, you can use the following command:

cat file1.txt file2.txt > combined.txt

1. To append the content of one file to another, you can use the append symbol (>>). For example, to append the content of file2.txt to the end of file1.txt, use the following command:

cat file2.txt >> file1.txt

1. To merge the contents of two files line by line, you can use the paste command. For example, to merge the contents of file1.txt and file2.txt line by line, use the following command:

paste file1.txt file2.txt > combined.txt

1. With the awk command, files can be merged and their content processed accordingly. For example, to merge the contents of file1.txt and file2.txt with a comma separator, use the following command:

awk 'BEGIN{OFS=","} NR==FNR{a[NR]=$0;next}{print a[FNR],$0}' file1.txt file2.txt > combined.txt

These are common file merging methods used in Linux systems. Choose the appropriate method based on specific needs.
