linux - Bash script not producing desired result -

-

i running cron-ed bash script extract cache hits , bytes served per ip address. script (proxyusage.bash) has 2 parts:

  1. (uniqueip.awk) find unique ips , create bash script add hits , bytes
  2. run hits , bytes per ip

proxyusage.bash

#!/usr/bin/env bash sudo gawk -f /home/maxg/scripts/uniqueip.awk /var/log/squid3/access.log.1 > /home/maxg/scripts/pxyusage.bash source /home/maxg/scripts/pxyusage.bash

uniqueip.awk

{   arrips[$3]++; }  end {    (n in arrips) {     m++;                               # count arrips elements     #print "array elements: " m;     arraddr[i++] = n;                  # fill arraddr ips     #print " " n;   }    asort(arraddr);                      # sort array values    (i = 1; <= m; i++) {           # write 1 command line per ip address     #printf("#!/usr/bin/env bash\n");     printf("sudo gawk -f /home/maxg/scripts/proxyusage.awk -v v_var=%s /var/log/squid3/access.log.1 >> /home/maxg/scripts/pxyusage.txt\n", arraddr[i])   } }

pxyusage.bash

sudo gawk -f /home/maxg/scripts/proxyusage.awk -v v_var=192.168.1.13 /var/log/squid3/access.log.1 >> /home/maxg/scripts/pxyusage.txt sudo gawk -f /home/maxg/scripts/proxyusage.awk -v v_var=192.168.1.14 /var/log/squid3/access.log.1 >> /home/maxg/scripts/pxyusage.txt sudo gawk -f /home/maxg/scripts/proxyusage.awk -v v_var=192.168.1.22 /var/log/squid3/access.log.1 >> /home/maxg/scripts/pxyusage.txt

theproxyusage.bash script runs scheduled , creates pxyusage.bash script. pxyusage.text file not amended latest values when script runs. far run pxyusage.bash every day myself, cannot figure out, why result not written file.

both bash scripts set execute. file permissions below:

-rwxr-xr-x  1 maxg maxg  169 mar 14 08:40 proxysummary.bash -rw-r--r--  1 maxg maxg  910 mar 15 17:15 proxyusage.awk -rwxrwxrwx  1 maxg maxg  399 mar 17 06:10 pxyusage.bash -rw-rw-rw-  1 maxg maxg 2922 mar 17 07:32 pxyusage.txt -rw-r--r--  1 maxg maxg  781 mar 16 07:35 uniqueip.awk

any hints appreciated. thanks.

the sudo(8) command requires pseudo-tty , not have 1 allocated under cron(8); do have 1 allocated when logged in usual way.

instead of mucking sudo(8), run script correct user.

if cannot that, in root crontab, this:

su - username /path/to/mycommand arg1 arg2...

this work because root can use su(1) without neding password.

[C++][SFML 2.2] Strange Performance Issues - Moving Mouse Lowers CPU Usage -

-
i've been working on making 2d map editor past 2 weeks or so, , i've run strange problem. trying optimize code, example, making functions should've been functions begin with, did made cpu usage go through roof. i've tried commenting out different sections of code thought culprits (scrolling, rendering, other calculations) no avail. think issue might trying call things within different functions, sake of making modular possible, i'd functionality. the other major change i've made since file i'm comparing i've ported variables external cpp file, since having variables global makes lot easier use within different functions. simple issue, can't life of me understand why happens. with original code, around 2-3% cpu usage. new code, around 20-35%, but, if move mouse around, it'll drop around 6-8%. tl;dr: after trying optimize code using functions, i've somehow killed performance, , found strange quirk moving mouse reduces cpu usage.. /...
