Try:
| Code: | | for i in $(grep -R -l PATTERN /PATH/*) ; do rm -i -- "$i" ; done |
or even shorter:
| Code: | | rm -i $(grep -R -l PATTERN /PATH/*) |

Is there a max number of arguments that can be given to programs? If you have that many mails then you might hit it. If the commands above yield too many matches, try to use xarg to delete them, something like | Code: | | grep -R -l PATTERN /PATH/* | xargs -rL 100 rm -i |
This will run 'rm' repeatedly with each at most 100 arguments. |

Yes, there is a maximum limit. GNU xargs can show the limit if you run xargs --show-limits. xargs is designed to compensate for this limit, so the only reason to restrict the number of arguments passed to the child program is if the child program cannot handle arbitrarily many arguments. As far as I know, rm has no such limitation, so you could just do xargs rm -i for the last portion of the pipeline. |

| Ah very cool. I didn't realize that xargs does that automatically when you specify no limits. (Feeling stupid that this wasn't obvious to me, as it makes a lot of sense.) |
