[opensuse] Scripting Question - Converting value to minutes:seconds
For all you scripting gurus out there. Can you help me out? I'm trying to convert a value to an output to the user of minutes:seconds. For example: if $A=100 (for seconds) Then echo "This is 1:40 minutes" How would I do this? -- ---Bryen--- -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

I'm not sure if there is some utility for converting directly to a time (I know there is in C, but I don't know about the shell) But otherwise, you could do something like echo This is $((A/60)):$((A%60)) minutes Anders -- Madness takes its toll -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

Not so difficult. -c tells the python interpreter to run the command or script as supplied. import time,sys tells python to use these two modules There is a commend, pydoc, which can be used to see what a python module does, so: $ pydoc time Help on module time: NAME time - This module provides various functions to manipulate time values. FILE /usr/lib/python2.5/lib-dynload/time.so MODULE DOCS http://www.python.org/doc/current/lib/module-time.html DESCRIPTION [..] Functions: [..] localtime() -- convert seconds since Epoch to local time tuple [..] FUNCTIONS localtime(...) localtime([seconds]) -> (tm_year,tm_mon,tm_day,tm_hour,\ tm_min,tm_sec,tm_wday,tm_yday,tm_isdst) $ pydoc sys Help on built-in module sys: NAME sys FILE (built-in) MODULE DOCS http://www.python.org/doc/current/lib/module-sys.html DESCRIPTION This module provides access to some objects used or maintained by the interpreter and to functions that interact strongly with the interpreter. Dynamic objects: argv -- command line arguments; argv[0] is the script pathname if known Thus the module time, called with function localtime(100), returns a list of values, of which tm_min (the 5th) and tm_sec (the 6th) are of interest. Because python counts from 0, and the intersection returns [from:to-1] the values in the list that you want are numbered [4:6]. localtime() wants a floating point number, thus the number from stdin is converted to float first. According to python's man-page, when python is called with -c and there are arguments after the commands, argv[0] holds '-c', argv[1] holds the first argument, argv[2] the 2nd etc. (My bad, the dash before $A was not needed afterall). This list (1,40) is fed to the printf style command, which prints the list as two seperate numbers. Python is a very usefull and powerfull language, with which you can do anything from these small oneliners to multi million Euro projects. The beauty of it is, that it's almost impossible to write unreadable code in Python. Theo -- Theo v.

For example: if $A=100 (for seconds)
A=100 notice this: $ echo $A $ $A=100 bash: =100: command not found $ A=DUMMY $ echo $A DUMMY $ $A=100 bash: DUMMY=100: command not found $
Then echo "This is 1:40 minutes"

If you want a pure shell scripting solution: -------------------------------------------- #!/bin/sh mysec=100 min=`expr $mysec / 60` sec=`expr 60 \* $min` sec=`expr $mysec - $sec` echo $min:$sec exit 0 -------------------------------------------- If you need more complicated math you can also try to employ bc (e.g. echo "100/60" | bc ; echo "100%60"| bc). See "man bc". Rgds, Stephan. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

But you have to write it like that (with spaces before and after the % !): sec=`expr $mysec % 60` Otherwise the modulus operation isn't executed. Thanks for the hint, Stephan. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

That's an interesting variation of the date command. And I'm certainly going to keep that in mind should the need for that type of variation arise. But in my script case, I was looking to convert a value into minutes/seconds not relative to clock time.

Now that was a fun one! :-) The earlier python one worked superbly as well, but this one I can understand it a little better and able to tweak it to my preferences/needs. Thanks man!
