% which bzip2

I am not sure what is happening here.

I used my current build and in the code told it to only use bzip2 by commenting out the other choices and setting bzip2 index to zero. It worked here.

type bzip2
bzip2 is /bin/bzip2

Care to try the development branch ?

I made no changes to the script, and the update fails with the same error message (yes, twice). Downloaded the Development branch copied GRC-Downloader.sh to my GRC folder and got the same error.

bzip2 is in /usr/bin/ as always.

I have not looked at a MacOS console in years. I'll have to get a virtual machine going to figure out what is differing.

Thanks for your feedback ! 👍

I'm having the same issue on Ubuntu 16.04. "No compression program found. Install a compression program like 7z or bzip2 to compress the cached search files."

I'm having the same issue on Linux Mint Cinnamon 19. Both 7z and bzip2 are already installed.

[sethleedy]

Yeah, need to parse this out. Checking into it.

I’ve been running the script on my synology, but it still fails to work on Mac OS (10.13 10.14 10.15)

Below is the bash -x output for 2.2. Seems like the arithmetic on chi_num is wrong.

+ check_program_exists_arr[0]=7z
+ check_program_exists_arr[1]=gzip
+ check_program_exists_arr[2]=zip
+ check_program_exists_arr[3]=bzip2
+ check_program_exists_arr[4]=p7zip
+ check_program_exists_multi 'check_program_exists_arr[@]'
+ check_program_exists_arr=("${!1}")
+ chi_num=0
+ for chi in "${check_program_exists_arr[@]}"
++ which 7z
+ chi_num=0+1

++ which gzip
+ chi_num=0+1+1

[sethleedy]

I'll take a look at it.
