You have multiple files in containing data in similar format and wanted to consolidate in a single file. This is usually the case if you have a daily log that you want to place an archive copy in a single file in weekly or in monthly, yearly.
The basic syntax of merging file is
cat >>
If you have more than 10 files to merge it is better to write a shell script that will loop through the files and merge in a file. The following is the code for merging the files in a folder into a single file.
#!/bin/sh echo enter file name read filename for arg in `ls;` do echo $arg cat $arg >> $filename done
Lines 2 and 3 prompts the user for the filename of the file which will contain the consolidated contents of all the files in the current folder.
Lines 5 to 9 loops through the files in the current folder and merge the files to a single file.
Simplest File Merging
#!/bin/sh echo enter file name read source_filemask read master_filename cat $arg >> $filename
A simple file merging
cat $* > $
Example
cat $Test* > $FinalTest.txt
