FOLDER(1mh) FOLDER(1mh) NAME folder, folders - set/list current nmh folder/message SYNOPSIS folder [-help] [-version] [+folder] [msg] [-all | -noall] [-create | -nocreate] [-fast | -no‐‐ fast] [-header | -noheader] [-recurse | -norecurse] [-total | -nototal] [-list | -no‐‐ list] [-push | -pop] [-pack | -nopack] [-print] [-verbose | -noverbose] folders is equivalent to folder -all DESCRIPTION When folder is given the -print switch (the default), it lists: the current folder, the num‐ ber of messages in it and their range (low-high), the folder's current message, and an indi‐ cation of extra files, if any. For example: inbox+ has 16 messages ( 3- 22); cur= 5. If a +folder and/or msg are specified, they will become the current folder and/or message. (When a +folder argument is given, this corresponds to a “cd” operation in the shell; when no +folder argument is given, this corresponds roughly to a “pwd” operation in the shell.) If the specified (or default) folder doesn't exist, folder will ask the user if the folder should be created; when standard input is not a tty, the answer is assumed to be “yes”. The -create switch tells folder to create new folders without query. (This is an easy way to create an empty folder for later use.) Specifying -nocreate will cause folder to print an error message and exit without creating a folder. Multiple Folders Specifying -all will produce a summary line for each top-level folder in the user's nmh di‐ rectory, sorted alphabetically. (If folder is invoked by a name ending with “s” (e.g. fold‐‐ ers), -all is assumed.) Specifying -recurse with -all will include a line for all sub-fold‐ ers. These folders are all preceded by any read-only folders, which occur as “atr-cur-” en‐ tries in the user's nmh context. For example: FOLDER # MESSAGES RANGE CUR (OTHERS) /var/work/folder has 35 messages ( 1- 35); cur=23. /usr/bugs/Mail has 82 messages ( 1-108); cur=82. ff has no messages. inbox+ has 16 messages ( 3- 22); cur= 5. mh has 76 messages (15- 76); cur=70. notes has 2 messages ( 1- 2); cur= 1. ucom has 124 messages ( 1-124); cur= 6; (others). TOTAL = 339 messages in 7 folders The “+” after inbox indicates that it is the current folder. The “(others)” indicates that the folder ucom contains files which aren't messages; these may either be sub-folders, or files that don't belong under the nmh file naming scheme. The header is output if either the -all or -header switches are specified. It is suppressed by -noheader. The folder and message totals are output if either the -all or -total switches are specified. They are suppressed by -nototal. If -fast is given, only the folder name (or names, in the case of -all) will be listed. (This is faster because the folders need not be read.) If a +folder is given with the -all switch, folder will, in addition to setting the current folder, list the top-level sub-folders for the current folder (with -norecurse) or list all sub-folders under the current folder recursively (with -recurse). If msg is supplied, together with +folder or without -all, it will become the current message of +folder (if it had been supplied) or the current folder. The -recurse switch lists each folder recursively, so its use effectively defeats the speed enhancement of -fast, since each folder must be searched for sub-folders. Nevertheless, the combination of these options is useful. Compacting a Folder The -pack switch will compress the message names in the designated folders, removing holes in message numbering. The -verbose switch directs folder to tell the user the general actions it is taking to compress the folder. The Folder Stack The -push switch directs folder to push the current folder onto the folder-stack, and make the +folder argument the current folder. If +folder is not given, the current folder and the top of the folder-stack are exchanged. This corresponds to the “pushd” operation in the shell. The -pop switch directs folder to discard the top of the folder-stack, after setting the cur‐ rent folder to that value. No +folder argument is allowed. This corresponds to the “popd” operation in the shell. The -push and -pop switches are mutually exclusive: the last occur‐ rence of either one overrides any previous occurrence of the other. The use of either of these switches also sets -list, by default. The -list switch directs folder to list the folder-stack. No +folder argument is allowed. After a successful -push or -pop, the -list action is taken, unless a -nolist switch follows them on the command line. This corresponds to the “dirs” operation in the shell. The -push, -pop, and -list switches all disable -print. FILES $HOME/.mh_profile The user's profile. PROFILE COMPONENTS Path: To determine the user's nmh directory. Current-Folder: To find the default current folder. Folder-Protect: To set mode when creating a new folder. Folder-Stack: To determine the folder stack. SEE ALSO mhpath(1), refile(1), rmf(1) DEFAULTS +folder The current folder. msg “none” -nofast -noheader -nototal -nopack -norecurse -noverbose -print is the default if no -list, -push, or -pop is specified. -list is the default if -push, or -pop is specified. CONTEXT If +folder and/or msg are given, they will become the current folder and/or message. BUGS There is no way to restore the default behavior (to ask the user whether to create a non-ex‐ istent folder) after -create or -nocreate is given. nmh-1.7.1 2016-08-29 FOLDER(1mh)
