shell - filter file content to sorted tables -

-

i have file contains following lines of code. here file displays schedules sorted 1 one . 

at 12:00 schedule of james version1 : first_task:eating:nothing second_task:rest:onehour third_task:watching:nothing   @ 12:00 schedule of james version2 : first_task:eating:fruits second_task:rest:twohour third_task:watching:manga   @ 12:00 schedule of alex version1 : first_task:eating:fruit second_task:rest:halfhour third_task:watching:horrorfilm   @ 12:00 schedule of alex version2 : first_task:eating:meal second_task:rest:nothing third_task:watching:nothing   @ 18:00 schedule of james version1 : first_task:eating:fastfood second_task:rest:twohours third_task:watching:series   @ 18:00 schedule of james version2 : first_task:eating:nothing second_task:rest:onehours third_task:watching:series   @ 18:00 schedule of alex version1 : first_task:eating:vegetals second_task:rest:threehours third_task:watching:manga   @ 18:00 schedule of alex version2 : first_task:eating:bread second_task:rest:fivehours third_task:watching:manga   @ 22:00 schedule of james version1 : first_task:eating:nothing second_task:rest:sevenhours third_task:watching:nothing  @ 22:00 schedule of james version2 : first_task:eating:meal second_task:rest:sixnhours third_task:watching:nothing  @ 22:00 schedule of alex version1 : first_task:eating:vegetals second_task:rest:sevehours third_task:watching:manga   @ 22:00 schedule of alex version2 : first_task:eating:icecream second_task:rest:sevenhours third_task:watching:nothing

i've tried sort way :

12:00 eating:fruit 18:00 eating:vegetals 22:00 eating:nothing  12:00 rest:onhour  18:00 rest:threehour 22:00 rest:sevenhour  12:00 watching:horrorfilm  18:00 watching:manga 22:00 watching:nothing

using these commands :

awk -f '[\ :]' '/the schedule is/{h=$2;m=$3} /eating/{print " "h":"m" watching:"$3}' f.txt awk -f '[\ :]' '/the schedule is/{h=$2;m=$3} /rest/{print " "h":"m" rest:"$3}' f.txt awk -f '[\ :]' '/the schedule is/{h=$2;m=$3} /watching/{print " "h":"m" watching:"$3}' f.txt

now looking improve filtered file ignoring non significant words , sorting valuable information in table , i've tried think/search how format in vain .

i have similar problem described in how prevent numbers being changed exponential form in python matplotlib figure : i don't want (in special case) weird scientific formatting of axis. problem different have problem @ z -axis. 2-d plots can use ax.get_yaxis().get_major_formatter().set_useoffset(false) . , there no function ax.get_zaxis() what use format z -axis same way? edit: example: from mpl_toolkits.mplot3d import axes3d import numpy np import sys import matplotlib import matplotlib.pyplot pyplot def func(xi, ti): res = 10e3 + np.cos(ti) * np.sin(xi) return res if __name__ == '__main__': timespacing = 20 timestart = 0 timeend = 1 time = np.linspace(timestart, timeend, timespacing) widthspacing = 50 widthstart = 0 widthend = 3 width = np.linspace(widthstart, widthend, widthspacing) reslist = [] matplotlib.rcparams['legend.fontsize'] = 10 fig = pyplot.figure() ax = fig.gca(projection = '3d...

i install web server database on raspberry pi (little computer). computer has 1gb ram. i want know best combination: linux distribution , web server , dbms run local server multiple users minimal latency, use php on server. , best settings performance , not have bugs (memory usage, disable plugin, disable service, etc)? i thought light debian , lighttpd server , sqlite database. solution? i think lighttpd + sqlite great choice. linux distro, debian @ centos or tiny core linux , although i'm not sure of compatibility pi. obviously, can't go wrong raspbian if want use in production , more stable performance, few more pi's , set them in cluster .
