bash 中 lib 的相对路径
relative path with lib in bash
我有一个脚本调用另一个脚本的函数。
我想在不同目录中的其他几个脚本中调用它。

[nir@dev nir]$ cat run_me.sh
echo working
[nir@dev nir]$ cat lib/lib.sh
run_me(){
echo $(realpath [=11=])
./run_me.sh
}
[nir@dev nir]$ cat a.sh
cd ` dirname "[=11=]" `
. ./lib/lib.sh
run_me
[nir@dev nir]$ cat b/a.sh
cd ` dirname "[=11=]" `
. ../lib/lib.sh
run_me
[nir@dev nir]$ ./a.sh
/tmp/nir/a.sh
working
[nir@dev nir]$ ./b/a.sh
realpath: ‘./b/a.sh’: No such file or directory
../lib/lib.sh: line 4: ./run_me.sh: No such file or directory
除了将函数移到 run_me.sh
中,我还有什么选择可以在 lib.sh
中修复它?
are my option to fix it within lib.sh?
相对于 lib.sh
调用它。例如:
run_me() {
"${BASH_SOURCE%/*}"/run_me.sh
}
您还可以将 lib.sh
的路径添加到 PATH
并让 Bash 搜索它。
