    Morning Ravi, I see what cat does and just wondered why when making a bootable usb pen-drive the code listed on most web-sites uses dd if=whatever.iso of=/dev/sdb, I read that dd copies saved files byte by byte probably from ascii coded text, how does cat work. I am a novice user of Linux, currently taking in all knowledge to gain my ” Red-Hat CSA”. I use your website daily, very informative chunk size blocks of data. Thank you

    Another one is writing ISO images to flash drives. Su to root and then, `cat fedora-24.iso > /dev/sdx`

    Thanks Ravi Saive for this article!!. One question, can I use the cat command to clone a partition with database files? like MySQL, or it’s works only if the original partition contains only text files?.

    • Ravi Saive says:


      In Linux everything is file, so the cat command will work on all types of files, whether it is database file or any file type extension, you can easily clone any partition..
