Switch to "exit" instead. - typeset -l makes the content lowercase, not the variable "local" (that's implied by using typeset.) Hence, drop it where inappropriate. - typeset -l is only available in BASH 4 and higher. Use it conditionally only. - Use tr to convert strings to lowercase when using a BASH version lower than 4. --- bin/debian-codename-to-version.sh | 14 +++++++++++--- bin/ubuntu-codename-to-version.sh | 14 +++++++++++--- 2 files changed, 22 insertions(+), 6 deletions(-) (limited to 'bin/ubuntu-codename-to-version.sh') diff --git a/bin/debian-codename-to-version.sh b/bin/debian-codename-to-version.sh index 8bd0384..42f497b 100755 --- a/bin/debian-codename-to-version.sh +++ b/bin/debian-codename-to-version.sh @@ -29,10 +29,18 @@ unset CDPATH # The return code is either 0, iff mapping was successful, # or 1 if the code name is unknown and mapping failed. -typeset -l codename +# Where supported (BASH 4 and higher), automatically +# lower-case the codename argument. +if [ -n "${BASH_VERSINFO[0]}" ] && [ "${BASH_VERSINFO[0]}" -gt 3 ]; then + typeset -l codename +fi codename="${1:?"No code name provided."}" -typeset -l -i ret="0" +if [ -z "${BASH_VERSINFO[0]}" ] || [ "${BASH_VERSINFO[0]}" -lt 4 ]; then + codename="$(tr '[:upper:]' '[:lower:]' <<< "${codename}")" +fi + +typeset -i ret="0" case "${codename}" in # The first version number is actually "fake", @@ -79,4 +87,4 @@ case "${codename}" in (*) ret="1";; esac -return "${ret}" +exit "${ret}" diff --git a/bin/ubuntu-codename-to-version.sh b/bin/ubuntu-codename-to-version.sh index 943e130..f2884cf 100755 --- a/bin/ubuntu-codename-to-version.sh +++ b/bin/ubuntu-codename-to-version.sh @@ -28,10 +28,18 @@ unset CDPATH # The return code is either 0, iff mapping was successful, # or 1 if the code name is unknown and mapping failed. -typeset -l codename +# Where supported (BASH 4 and higher), automatically +# lower-case the codename argument. +if [ -n "${BASH_VERSINFO[0]}" ] && [ "${BASH_VERSINFO[0]}" -gt 3 ]; then + typeset -l codename +fi codename="${1:?"No code name provided."}" -typeset -l -i ret="0" +if [ -z "${BASH_VERSINFO[0]}" ] || [ "${BASH_VERSINFO[0]}" -lt 4 ]; then + codename="$(tr '[:upper:]' '[:lower:]' <<< "${codename}")" +fi + +typeset -i ret="0" case "${codename}" in # The first version number is actually "fake", @@ -69,4 +77,4 @@ case "${codename}" in (*) ret="1";; esac -return "${ret}" +exit "${ret}" -- cgit v1.2.3
