I am trying to get this sed command to work:

   sed -e 

     's|$API_URL|$(API_URL)|g ; 

      s|$API_KEY|$(API_KEY)|g ;  

      s|$API_SECRET|$(API_SECRET)|g ;  

      s|$API_SALT|$(API_SALT)|g ; 

      s|$STORAGE_FUNCTION|$(STORAGE_FUNCTION)|g ; 

      s|$STORAGE_ACCOUNT|$(STORAGE_ACCOUNT)|g ; 

      s|$STORAGE_CONTAINER|$(STORAGE_CONTAINER)|g' 

      ./src/environments/environment.template.ts > ./src/environments/environment.ts

I am replacing placeholders in a file:

export const environment = {

   api: {

     url: '$API_URL',

     key: '$API_KEY',

     secret: '$API_SECRET',

     salt: '$API_SALT'

   }

};

But I get this error:

newline can not be used as a string delimiter

The actual error comes from the fact that an arbitrary delimiter character may be used to delimit a regular expression when used as line addresses by prefixing the delimiter character with a backslash, as in

@hello@d

which would delete each line matching the regular expression hello, just like

/hello/d

would.

However, newlines may not be used as a delimiter in this way. Hence the error.

The sed script does not need the escaped newlines as it is all within a single quoted string. Remove the at the end of each line of the actual sed editing script:

sed -e 's|$API_URL|$(API_URL)|g

        s|$API_KEY|$(API_KEY)|g

        s|$API_SECRET|$(API_SECRET)|g

        s|$API_SALT|$(API_SALT)|g

        s|$STORAGE_FUNCTION|$(STORAGE_FUNCTION)|g

        s|$STORAGE_ACCOUNT|$(STORAGE_ACCOUNT)|g

        s|$STORAGE_CONTAINER|$(STORAGE_CONTAINER)|g' 

    infile >outfile

Note that the ; between statements are replaced by newlines. They are only needed between statements occupying the same line, as in G;s/n/ /, for example.

Alternatively:

sed -e 's|$API_URL|$(API_URL)|g' 

    -e 's|$API_KEY|$(API_KEY)|g' 

    -e 's|$API_SECRET|$(API_SECRET)|g' 

    -e 's|$API_SALT|$(API_SALT)|g' 

    -e 's|$STORAGE_FUNCTION|$(STORAGE_FUNCTION)|g' 

    -e 's|$STORAGE_ACCOUNT|$(STORAGE_ACCOUNT)|g' 

    -e 's|$STORAGE_CONTAINER|$(STORAGE_CONTAINER)|g' 

    infile >outfile

Or,

sed "s/'\$([^']*)'/'$(1)'/g" infile >outfile

to replace anything that looks like '$something Whatever' with '$(something Whatever)'.

Or,

sed 's/$([A-Z_]*)/$(1)/g' infile >outfile

to replace things that look like $SOME_THING with $(SOME_THING) (slightly stricter on the allowed characters in the variable names, but does not care about the single quotes).
