I am attempting to write a BASH script to return the following information from CPUINFO using the following commands

  • ./systemstat.sh -r to return the time along with total number of eth0 packets.
  • ./systemstat -c to return the vendor_id= and cpu MHz=.

When I use those commands, I recieve -bash: ./systemstat.sh: No such file or directory.

This is because you don't have systemstat.sh in your current directory .. The dot means the "current directory" or "working directory". If you do ls . you will notice that the script isn't there. For running this script you should either use:

  • the full path /path/to/script/systemstat.sh
  • copying them to a bin directory cp systemstat.sh /usr/local/bin/ then run without the dot: systemstat.sh
  • Or adding the directory where the script is to the path PATH=/path/to/script:$PATH and then execute the script without the dot.
  • or move your working directory to were the script is cd /path/to/script && ./systemstat.sh
