En regardant cette sortie, j'ai décidé de commencer mc
avec empty PROMPT_COMMAND
( PROMPT_COMMAND= mc
), et cela a commencé instantanément. J'avais là soi-disant commun:
history -a; history -c; history -r;
UPD Après quelques recherches supplémentaires, il s'avère que cela n'a rien à voir avec l'histoire ( PROMPT_COMMAND=';' strace -r -tt -o mc.strace -s 1000 mc
):

Ma conjoncture est que mc
dérange d' PROMPT_COMMAND
une mauvaise façon. Il change de PROMPT_COMMAND
sorte que s'il contient ;
, cela déclenche une erreur bash. En tant que tel, rien n'est écrit dans le descripteur 8
, ce qui bloque le processus jusqu'à l'expiration du délai. Corrige moi si je me trompe.
--enable-vfs-smb
? Essayez de désactiver la fonction. Semble être un problème commun avec la version 4.8.4: le démarrage de mc est très lent
