Command line is the most powerful tool there is, in Linux. You can do anything and everything with the command line utility tools under Linux. cat is an awesome command line utility tool. It’s used to concatenate files. I had 300+ contact numbers in separate .vcf files and Google Contacts only allows to import only one .vcf file at a time. And apparently it’s next to impossible for a guy like me to import those 300+ .vcf files one by one. Therefore, I needed to convert those .vcf files into a single .vcf file so that I could import them in Google Contacts. I searched the net and found some solution on how to do that using Windows. And I thought if one can do this on Windows, then it’s a sure shot for Linux. And then a thought came to my mind.
I was familiar with the cat command. And I knew it’s power. I just executed the command using cat and voila!
So here’s the format to merge multiple .vcf file into a single .vcf file:
cat *.vcf > mergedfile.vcf
Here, the asterisk (*) mark denotes every file names ended with .vcf extension. And you can give any name to your merged file.
Copy all the files to a single folder/directory before executing the command. And make sure to direct your terminal to that directory i.e. open terminal window in that folder.
Use man cat in terminal to know more about the cat command.
