Sometimes it’s needed to create multiple files, repeatadly with linux. This should work with any of the major distros: CentOS, Ubuntu, Fedora, Debian, etc.
This also assumes the file does not exist already, if it does exist, it will append this info to the end of the file that already exists.
cat >> ifcfg-eth0 << EOF TYPE=Ethernet DEVICE=eth0 BOOTPROTO=none ONBOOT=yes EOF
You can now type cat ifcfg-eth0 and it will output the 4 lines above.
If that is not to your liking, you could always use something like echo with append statements. Like this:
echo "TYPE=Ethernet" >> ifcfg-eth0 echo "DEVICE=eth0" >> ifcfg-eth0 echo "BOOTPROTO=none" >> ifcfg-eth0 echo "ONBOOT=yes" >> ifcfg-eth0
The >> option appends the echo information into a file name. But if you do > it will overwrite all lines in the file.
