if the call to callee.sh is hanging with parameters, try executing it outside the script with parameters and check if it is hanging there as well… Anyways, the best way of saving output (and printing it out afterwards): result=”$(./callee.sh param1 param2 param2)” echo “${result}” <— this should show the line breaks 1 solved Bash – … Read more
A very small rounding difference, within the range possible for the difference between 64 and 80 bits, could account for the different output. The combination of the truncate to int and shift can magnify a tiny difference. This program: #include <stdio.h> int main(){ double zaehler = -20; double teiler = 0.08; printf(“ergebnis = %d \n”, … Read more

Make a bash script. LOGIC: Use netstat -natp (filter it through awk/sed to get the ports, then grep it) Then use a simple test to see if the result was empty. Run curl if it was. Put this in a cron job. Simple stuff, really. EDIT: netstat is a utility which will show you all … Read more
PHP 5.3 has different operator precedence to 7.x, if memory serves. So retaining the PHP version would be a problem. Plugins should work exactly the same between different OSes providing that permissions are the same. Changing between Apache and Nginx can break them if they’re dependent on rewrites/.htaccess. I hope that helps. solved Can super … Read more
I’m assuming the input is always two columns, the first column contains the column headers of the output repeated over and over, and that the output may contain one or more columns. $ cat t.awk { sep = (FNR % n == 0) ? “\n” : ” ” } NR==FNR { printf $1 sep; if … Read more

Userspace programs do exist in the Linux kernel source tree in the tools/ subdirectory. There does not seem to be a clear-cut (or any) definition of what kind of program constitutes a “tool” that requires/deserves inclusion/distribution with the kernel source. The types of utilities that do (currently) exist in the kernel source tree include an … Read more
You need to use an array, not a regular variable. curl_std_opts=( -k –header ‘Content-Type: application/json’ –header ‘Accept: application/json’) curl “${curl_std_opts[@]}” -X POST –data “{\”actual\”: $BAL}” “$websiteurl” For safety, you should use a tool like jq to generate your JSON rather than relying on parameter interpolation to generate valid JSON. curl “${curl_std_opts[@]}” -X POST –data “(jq … Read more
