Linux Helpful Commands

Here is a list of some helpful Linux commands (all these commands assume you are a ROOT user):

• Need to search all your files, on your server for a word(s)?
  • grep -r "SEARCH WORDS HERE" .
    • Add on "-l" if you want to return ONLY the file that search word is in.
    • Add on "-i" if you want to make it case insensitive.
  • Tip: make sure to end with the "." as it is the wild card that will search all file types.

• Need to move all files from a old Linux server to a new one using SSH?
  • scp -rC USER@DOMAIN:/DIRECTORY TO COPY .
  • Tips:
    • -r is for recursive
    • -C is for compression on fly (10x faster transfer)
    • For DOMAIN use either FQDN or IP of old server
    • Make sure to end your directory with "." as it is the wild card to transfer all file types.
