How can I build an env file (with $ characters) listing as-is from echo command?
I am trying to build a file invoked from a script that echoes what is in quotes to a file - only, the $ gets omitted.
This is what I was trying to do:
echo -e "export ORACLE_BASE=/oracle/APP/grid n
export ORACLE_HOME=/oracle/APP/grid/12.1.0/gridn
export PATH=$ORACLE_HOME/bin:$PATHn export ORACLE_SID=+ASM”>/home/oragrid/ASM.env
But it doesn't quite echo into the file.
echo variable-substitution

Don't use echo -e in scripts aimed at portability. Use the shell built-in printf() which does everything as the former and still remains compliant across shells. For your requirement though, to store a multi-line string without expanding variables prefixed with $, use a here-doc
cat << 'EOF' > /home/oragrid/ASM.env
export ORACLE_BASE=/oracle/APP/grid
export ORACLE_HOME=/oracle/APP/grid/12.1.0/grid
export PATH=$ORACLE_HOME/bin:$PATH
export ORACLE_SID=+ASM
EOF
This would keep all the content within EOF intact, not expanding the variables inside.
