shell-like commandline handling.
mchars) ⇒ (ret
Quotes a string so that the shell (/bin/sh) will interpret the quoted string to mean unquoted-string. If you pass a filename to the shell, for example, you should first quote it with this function. The return value must be freed with
g-free. The quoting style used is undefined (single or double quotes may be used).
- a literal string
- quoted string
mchars) ⇒ (ret
Unquotes a string as the shell (/bin/sh) would. Only handles quotes; if a string contains file globs, arithmetic operators, variables, backticks, redirections, or other special-to-the-shell features, the result will be different from the result a real shell would produce (the variables, backticks, etc. will be passed through literally instead of being expanded). This function is guaranteed to succeed if applied to the result of
g-shell-quote. If it fails, it returns ‘
#f’ and sets the error. The quoted-string need not actually contain quoted or escaped text;
g-shell-unquotesimply goes through the string and unquotes/unescapes anything that the shell would. Both single and double quotes are handled, as are escapes including escaped newlines. The return value must be freed with
g-free. Possible errors are in the
Shell quoting rules are a bit strange. Single quotes preserve the literal string exactly. escape sequences are not allowed; not even \' - if you want a ' in the quoted text, you have to do something like 'foo'\”bar'. Double quotes allow $, `, ", \, and newline to be escaped with backslash. Otherwise double quotes preserve things literally.
- shell-quoted string
- error return location or NULL
- an unquoted string
