How to write multiple lines to a bash file?

Question

linux

Tell me how you can write multiple lines to a file through the command line?
Example:

echo “
«Строка 1
Строка 2
Строка3» >> /home/2.txt

Each line with a new line
Maybe echo should not be used

Answer 1

cat << EOF > your_file.txt
str1
str2
str3
EOF

Oh, well, you can echo:

echo "str1
str2
str3" >> myfile.txt

Answer 2

cat > /etc/sysconfig/network-scripts/ifcfg-"${nameINT}" <<EOF
NAME="${nameINT}"
DEVICE="${nameINT}"
BOOTPROTO=static
UUID="${uuid}"
ONBOOT=yes
IPADDR="${1}"
NETMASK="${NETMASK}"
EOF

you can also do this if the lines are short
printf "str1\nstr2\nstr3" >> /home/2.txt

In addition to the above:
echo -e "str1\nstr2\nstr3" >> file.txt
