Generating command arguments with a loop in bash -

Is it possible to put a loop inside my code? Want to plot a field for every day of the current month and save a file? One way is difficult, but it is not fun, and due to the number of days of each month is impractical. Want to do something like "every day of the mont ..." or "while the day lt; lastDay ...."

Any good luck

  $ ./simple_bar_generator.sh ./simple_bar_generator.sh: line 31: unexpected token Pass syntax error `` tax./simple_bar_generator.sh: line 31: `while [$ first del-la $ last day]; Do ' 

The last loop looks like this: Adding an index to the variable does not accept the reuse of the rrdtool variable.

  args = () day = $ firstDay i = 1 while [[$ day! = $ (Date -d "$ last day + 1 day" +% Y% m% d)]]; Do day = $ (date -d "$ day + 1 days" +% Y% m% d) args + = (def: original $ i = "$ powerDBPath: $ DS: average: start = $ day: end = $ DayStop "CDEF: w $ = i note $ i, 3600," * "CDEF: energiK $ i = tot $ i, 1000, / VDEF: value_sum $ i = energiK $ i, total CDEF: value_area $ i = w $ i , W $ i, -, value_sum $ i, + area: value_area $ i # aaaai line1: value_area $ i # 000000 GPRINT: value_sum $ i: "Forwarding (for testing) $ day% 0.2lfkWh \ n") day = $ (Date-D "$ day + 1 day" +% Y% m% d) I = $ [$ i + 1]
