錯誤而採購shell腳本

Question

爲了完成安裝，我需要源的以下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 

但是當我採購它，我得到以下錯誤：

() not correctly positioned 

任何想法爲什麼？ 奇怪的是，當我在一個集羣上操作時，發生了這個錯誤，而我的電腦上沒有它。

編輯：

的lsb_release -a的輸出是：

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 

的echo $0輸出是-tcsh。

Answer 1

我想你正在使用不同的shell（tcsh）而不是sh或bash。很可能你必須修改你的源代碼才能使用tcsh加載它。在sh/bash下正常工作

root@pve1:~# echo $0 
-bash 

Answer 2

在bash中，您的腳本在語法上是正確的。但是如果你使用sh，那麼有一些錯誤。檢查shellcheck輸出：

$ 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. 

總結：不需要

• function關鍵字（甚至推薦）
• local在POSIX不支持sh
• 字符串替換${//}不支持sh。
