I noticed a couple of inconsistencies when reading through the install bash scripts. - Make documentation for switches consistent over all files. - Replace all `sed` implementations of `lowercase` with a more maintainable `tr` implementation. - Set the `OS` variable in every install script, making it so previously unused checks are actually used. - Exit with a non-zero exit code when the script reaches an illegal state. ## PR Context A lot of people, including myself, read the install scripts before executing them. While doing so I noticed they contained inconsistencies. For example, certain flags you can pass to the install script were either undocumented or had an incorrect description. This PR fixes some of these inconsistencies, which should make them easier to maintain and easier to read. Co-authored-by: Travis Plunk <github@ez13.net>

#Companion code for the blog https://cloudywindows.com
|
|
#call this code direction from the web with:
|
|
#bash <(wget -O - https://raw.githubusercontent.com/PowerShell/PowerShell/master/tools/installpsh-redhat.sh) ARGUMENTS
|
|
#bash <(curl -s https://raw.githubusercontent.com/PowerShell/PowerShell/master/tools/installpsh-redhat.sh) <ARGUMENTS>

|
#Usage - if you do not have the ability to run scripts directly from the web,
|
|
# pull all files in this repo folder and execute, this script
|
|
# automatically prefers local copies of sub-scripts
|
|
|
|
#Completely automated install requires a root account or sudo with a password requirement
|
|
|
|
#Switches
|
|
# -includeide - installs VSCode and VSCode PowerShell extension (only relevant to machines with desktop environment)
|
|
# -interactivetesting - do a quick launch test of VSCode (only relevant when used with -includeide)
|
|
# -skip-sudo-check - use sudo without verifying its availability (this is required to run in the VSTS Hosted Linux Preview)
|
|
# -preview - installs the latest preview release of PowerShell core side-by-side with any existing production releases
|
|
|
|
#gitrepo paths are overrideable to run from your own fork or branch for testing or private distribution
