It looks like a bash command, if you make the following changes: 1) Join the two lines into one. 2) Remove leading / and trailing / characters. Also, I don't have a /var/log/installer/initial-status.gz file, but I do have a /var/log/installer/status file, which looks like it contains what the command is expecting (minus the compression). So, one might need to adjust the second process substitution.
