 hg verify
 
 verify the integrity of the repository
 
     Verify the integrity of the current repository.
 
     This will perform an extensive check of the repository's integrity,
     validating the hashes and checksums of each entry in the changelog,
     manifest, and tracked files, as well as the integrity of their crosslinks
     and indices.
 
 use "hg -v help verify" to show global options
 hg diff [OPTION]... [-r REV1 [-r REV2]] [FILE]...
 
 diff repository (or selected files)
 
     Show differences between revisions for the specified files.
 
     Differences between files are shown using the unified diff format.
 
     NOTE: diff may generate unexpected results for merges, as it will default
     to comparing against the working directory's first parent changeset if no
     revisions are specified.
 
     When two revision arguments are given, then changes are shown between
     those revisions. If only one revision is specified then that revision is
     compared to the working directory, and, when no revisions are specified,
     the working directory files are compared to its parent.
 
     Without the -a/--text option, diff will avoid generating diffs of files it
     detects as binary. With -a, diff will generate a diff anyway, probably
     with undesirable results.
 
     Use the -g/--git option to generate diffs in the git extended diff format.
     For more information, read 'hg help diffs'.
 
 options:
 
  -r --rev                  revision
  -c --change               change made by revision
  -a --text                 treat all files as text
  -g --git                  use git extended diff format
     --nodates              don't include dates in diff headers
  -p --show-function        show which function each change is in
     --reverse              produce a diff that undoes the changes
  -w --ignore-all-space     ignore white space when comparing lines
  -b --ignore-space-change  ignore changes in the amount of white space
  -B --ignore-blank-lines   ignore changes whose lines are all blank
  -U --unified              number of lines of context to show
     --stat                 output diffstat-style summary of changes
  -I --include              include names matching the given patterns
  -X --exclude              exclude names matching the given patterns
 
 use "hg -v help diff" to show global options
 hg status [OPTION]... [FILE]...
 
 aliases: st
 
 show changed files in the working directory
 
     Show status of files in the repository. If names are given, only files
     that match are shown. Files that are clean or ignored or the source of a
     copy/move operation, are not listed unless -c/--clean, -i/--ignored,
     -C/--copies or -A/--all are given. Unless options described with "show
     only ..." are given, the options -mardu are used.
 
     Option -q/--quiet hides untracked (unknown and ignored) files unless
     explicitly requested with -u/--unknown or -i/--ignored.
 
     NOTE: status may appear to disagree with diff if permissions have changed
     or a merge has occurred. The standard diff format does not report
     permission changes and diff only reports changes relative to one merge
     parent.
 
     If one revision is given, it is used as the base revision. If two
     revisions are given, the differences between them are shown. The --change
     option can also be used as a shortcut to list the changed files of a
     revision from its first parent.
 
     The codes used to show the status of files are:
 
       M = modified
       A = added
       R = removed
       C = clean
       ! = missing (deleted by non-hg command, but still tracked)
       ? = not tracked
       I = ignored
         = origin of the previous file listed as A (added)
 
 options:
 
  -A --all        show status of all files
  -m --modified   show only modified files
  -a --added      show only added files
  -r --removed    show only removed files
  -d --deleted    show only deleted (but tracked) files
  -c --clean      show only files without changes
  -u --unknown    show only unknown (not tracked) files
  -i --ignored    show only ignored files
  -n --no-status  hide status prefix
  -C --copies     show source of copied files
  -0 --print0     end filenames with NUL, for use with xargs
     --rev        show difference from revision
     --change     list the changed files of a revision
  -I --include    include names matching the given patterns
  -X --exclude    exclude names matching the given patterns
