php - Bash one liner - 测试一个文件是否存在，如果它有其他错误退出

Question

换句话说，我想把它做成单行:

    test -e ${MY_HOME}/setup-env.sh || { echo "ERROR: MY_HOME not defined or does not contain srtup-env.sh" 1>&2 ; exit 1; }

    . ${MY_HOME}/setup-env.sh

Answer 1

你可以使用这个衬垫:

[[ -e "${MY_HOME}/setup-env.sh" ]] && source "${MY_HOME}/setup-env.sh" || { echo "ERROR: MY_HOME not defined or does not contain srtup-env.sh" 1>&2 ; exit 1; }
