Question

为了完成安装，我需要获取以下.sh文件：

function addvar () {
local tmp="${!1}" ;
tmp="${tmp//:${2}:/:}" ; tmp="${tmp/#${2}:/}" ; tmp="${tmp/%:${2}/}" ;
export $1="${2}:${tmp}" ;
} 

if [ -z "${PATH}" ]; then 
PATH=/share/MontePython/plc-2.0/bin
export PATH
else
addvar PATH /share/MontePython/plc-2.0/bin
fi
if [ -z "${PYTHONPATH}" ]; then 
PYTHONPATH=/share/MontePython/plc-2.0/lib/python2.7/site-packages
export PYTHONPATH
else
addvar PYTHONPATH /share/MontePython/plc-2.0/lib/python2.7/site-packages
fi
if [ -z "${LD_LIBRARY_PATH}" ]; then 
LD_LIBRARY_PATH=/share/apps/intel/l_ics_2015.1.133/composer_xe_2015.1.133/ipp/../compiler/lib/intel64
export LD_LIBRARY_PATH
else
addvar LD_LIBRARY_PATH /share/apps/intel/l_ics_2015.1.133/composer_xe_2015.1.133/ipp/../compiler/lib/intel64
fi
if [ -z "${LD_LIBRARY_PATH}" ]; then 
LD_LIBRARY_PATH=/share/apps/intel/l_ics_2015.1.133/composer_xe_2015.1.133/compiler/lib/intel64/
export LD_LIBRARY_PATH
else
addvar LD_LIBRARY_PATH /share/apps/intel/l_ics_2015.1.133/composer_xe_2015.1.133/compiler/lib/intel64/
fi
if [ -z "${LD_LIBRARY_PATH}" ]; then 
LD_LIBRARY_PATH=/share/apps/intel/l_ics_2015.1.133/composer_xe_2015.1.133/compiler/lib/intel64
export LD_LIBRARY_PATH
else
addvar LD_LIBRARY_PATH /share/apps/intel/l_ics_2015.1.133/composer_xe_2015.1.133/compiler/lib/intel64
fi
if [ -z "${LD_LIBRARY_PATH}" ]; then 
LD_LIBRARY_PATH=/lib64
export LD_LIBRARY_PATH
else
addvar LD_LIBRARY_PATH /lib64
fi
if [ -z "${LD_LIBRARY_PATH}" ]; then 
LD_LIBRARY_PATH=/lib
export LD_LIBRARY_PATH
else
addvar LD_LIBRARY_PATH /lib
fi
if [ -z "${LD_LIBRARY_PATH}" ]; then 
LD_LIBRARY_PATH=/share/apps/intel/l_ics_2015.1.133/composer_xe_2015.1.133/ipp/../compiler/lib/intel64/
export LD_LIBRARY_PATH
else
addvar LD_LIBRARY_PATH /share/apps/intel/l_ics_2015.1.133/composer_xe_2015.1.133/ipp/../compiler/lib/intel64/
fi
if [ -z "${LD_LIBRARY_PATH}" ]; then 
LD_LIBRARY_PATH=/share/MontePython/plc-2.0/lib
export LD_LIBRARY_PATH
else
addvar LD_LIBRARY_PATH /share/MontePython/plc-2.0/lib
fi
CLIK_PATH=/share/MontePython/plc-2.0
export CLIK_PATH

CLIK_DATA=/share/MontePython/plc-2.0/share/clik
export CLIK_DATA

CLIK_PLUGIN=rel2015
export CLIK_PLUGIN

但是当我采购它时，我收到以下错误：

() not correctly positioned

知道为什么吗？奇怪的是，当我在群集上操作时会发生这种错误，而我的PC上却没有。

编辑：

lsb_release -a的输出是：

LSB Version:    :base-4.0-amd64:base-4.0-noarch:core-4.0-amd64:core-4.0-noarch:graphics-4.0-amd64:graphics-4.0-noarch:printing-4.0-amd64:printing-4.0-noarch
Distributor ID: CentOS
Description:    CentOS release 6.9 (Final)
Release:    6.9
Codename:   Final

echo $0的输出为-tcsh。

Answer 1

我认为你使用的是另一个shell（tcsh）而不是sh或bash。很可能你必须调整源代码以使用tcsh加载它。在sh / bash下工作正常

root@pve1:~# echo $0
-bash

Answer 2

在bash中，您的脚本在语法上是正确的。但是，如果您使用sh，则会出现一些错误。检查shellcheck输出：

$ shellcheck script.sh 

In script.sh line 3:
function addvar () {
^-- SC2112: 'function' keyword is non-standard. Delete it.


In script.sh line 4:
local tmp="${!1}" ;
^-- SC2039: In POSIX sh, 'local' is undefined.
           ^-- SC2039: In POSIX sh, indirect expansion is undefined.


In script.sh line 5:
tmp="${tmp//:${2}:/:}" ; tmp="${tmp/#${2}:/}" ; tmp="${tmp/%:${2}/}" ;
     ^-- SC2039: In POSIX sh, string replacement is undefined.
                              ^-- SC2039: In POSIX sh, string replacement is undefined.
                                                     ^-- SC2039: In POSIX sh, string replacement is undefined.

总结：

function关键字不需要（甚至不推荐）

local

sh {li> ${//}
字符串替换sh

在获取shell脚本时出错
