The third argument above, "push....", will be evaluated twice by the muttrc parser.
The first time, when reading the line out of your muttrc file. The parser will extract three arguments:
folder-hook fa-ml push <delete-pattern>~b"^@[a-zA-Z0-9_]+ pushed [0-9]+ commits?.$"!~F<enter>Note when the third argument was parsed, the single quotes are not included in the result - they are used to evaluate the argument in "single quotes" mode during parsing.
Mutt uses this to create a folder hook, matching against 'fa-ml', and will parse and run the third argument when the hook runs.
So, when the folder hook actually runs, the muttrc parser will extract two arguments: push <delete-pattern>~b^@[a-zA-Z0-9_]+ pushed [0-9]+ commits?.$!~F<enter> Note the double quotes are not included in the result, they (again) are used to evaluate their contents in "double quotes" mode during parsing. You could try putting a backslash in front of each double quote: folder-hook fa-ml 'push <delete-pattern>~b\"^@[a-zA-Z0-9_]+ pushed [0-9]+ commits?.$\"!~F<enter>' Or alternatively, add an escaped single quote around the second argument: folder-hook fa-ml 'push '\''<delete-pattern>~b"^@[a-zA-Z0-9_]+ pushed [0-9]+ commits?.$"!~F<enter>'\' When this line is first parsed, it will be the three arguments: folder-hook fa-ml push '<delete-pattern>~b"^@[a-zA-Z0-9_]+ pushed [0-9]+ commits?.$"!~F<enter>' And when the hook is run, it will parse two arguments: push <delete-pattern>~b"^@[a-zA-Z0-9_]+ pushed [0-9]+ commits?.$"!~F<enter>I haven't actually tested anything here (so there may be some typos), but hopefully that will get you going in the right direction to debug things.
