Подпишись 👉@i_DevOpsecho "Input string here" | tr '[:upper:]' '[:lower:]'
Давайте создадим пример скрипта.
Инициализируйте переменную строкой с несколькими заглавными буквами.
Затем преобразуйте все буквы в строчные и сохраните их в другой переменной.
#!/usr/bin/env bash
str=“Hello World”
lowerStr=$(echo “$str” | tr ‘[:upper:]’ ‘[:lower:]’)
echo “Input String: $str”
echo “Result String: $lowerStr”
Результат
Input String: Hello World
Result String: hello world
👉 @sysadminof# apt install autoconf gcc make git
# git clone https://github.com/open-ch/log-user-session
# cd open-ch/log-user-session
# ./autogen.sh
# ./configure
# make
# make install
Далее в sshd_config нужно добавить параметр:
ForceCommand /usr/local/bin/log-user-session
Теперь у каждого пользователя будет запускаться оболочка через log-user-session
