The s6-quote-filter program

s6-quote-filter acts as a filter, quoting lines it reads on stdin and writing the quoted lines to stdout.

Interface

     s6-quote-filter [ -u ] [ -d delim ]

• s6-quote reads lines on stdin; it quotes every line, putting it inside double quotes and escaping all dubious characters
• It writes the quoted strings to stdout
• It exits 0 on EOF

Options

• -u : do not put read lines inside double quotes, only escape characters if needed
• -d delim : use the first character of delim as a quote character, instead of double quotes

Notes

• Quoted strings are guaranteed to be pure printable ASCII, without control characters.
• Quoted strings can be unquoted via the s6-unquote or s6-unquote-filter programs.
