Basic options:\n\
-h, --help display this help text\n\
-v, --version show version information\n\
-i, --init FILE initialize ledger by loading FILE (def: ~/.ledgerrc)\n\
--cache FILE use FILE as a binary cache when --file is not used\n\
-f, --file FILE read ledger data from FILE\n\
-o, --output FILE write output to FILE\n\
-z, --set-price CONV specify a commodity conversion: \"COMM=AMOUNT\"\n\
-a, --account NAME specify the default account (useful with QIF files)\n\n\
Report filtering:\n\
-b, --begin-date DATE set report begin date\n\
-e, --end-date DATE set report end date\n\
-c, --current show only current and past entries (not future)\n\
-C, --cleared consider only cleared transactions\n\
-U, --uncleared consider only uncleared transactions\n\
-R, --real consider only non-virtual transactions\n\
-r, --related calculate report using related transactions\n\n\
Output customization:\n\
-F, --format STR use STR as the format; for each report type, use:\n\
--balance-format --equity-format\n\
--register-format --plot-value-format\n\
--print-format --plot-total-format\n\
-y, --date-format STR use STR as the date format (def: %Y/%m/%d)\n\
-E, --empty balance: show accounts with zero balance\n\
-n, --collapse register: collapse entries with multiple transactions\n\
-s, --subtotal balance: show sub-accounts; register: show subtotals\n\
-S, --sort EXPR sort report according to the value expression EXPR\n\
-p, --interval STR report by interval (period), based on STR\n\
--dow show a days-of-the-week report\n\
-W, --weekly show weekly sub-totals\n\
-M, --monthly show monthly sub-totals\n\
-Y, --yearly show yearly sub-totals\n\
-l, --limit EXPR calculate only transactions matching EXPR\n\
-d, --display EXPR display only transactions matching EXPR\n\
-t, --value-expr EXPR set the value expression for all report types\n\
-T, --total-expr EXPR set the total expression for all report types\n\
-j, --value-data print only raw value data (useful when scripting)\n\
-J, --total-data print only raw total data\n\n\
Commodity reporting:\n\
-P, --price-db FILE sets the price database to FILE (def: ~/.pricedb)\n\
-L, --price-exp MINS download quotes only if newer than MINS (def: 1440)\n\
-Q, --download download price information when needed\n\
-O, --quantity report commodity totals (this is the default)\n\
-B, --basis report commodity cost basis\n\
-V, --market report commodity market value\n\
-G, --gain report commodity gain/loss\n\
-A, --average report average transaction amount\n\
-D, --deviation report deviation from the average\n\
-X, --trend report average deviation from the average\n\
-Z, --weighted-trend same as trend, but older values are less significant\n\
(-D, -X and -Z make little sense in balance reports)\n\
Commands:\n\
balance [REGEXP]... show balance totals for matching accounts\n\
register [REGEXP]... show register of matching transactions\n\
print [REGEXP]... print all matching entries\n\
equity [REGEXP]... output equity entries for matching accounts\n\
entry DATE PAYEE AMT output a derived entry, based on the arguments\n";
