无法将变量设置为C-shell的脚本

问题描述

这很简单。我试图在第二个脚本中设置变量。我尝试了多种方法，但没有用。因此，所有注释掉的部分。运行IE：unit3.2a.sh 3的第一个脚本3将返回8。第二个脚本应将结果读取为8。我正在使用cygwin。

unit3.2a.sh '''

#!/bin/csh

set a = 0
set b = 0
set c = 0

@ a = $1
@ b = $2

@ c = $a + $b

echo $c

'''

unit3.sh '''

#!/bin/csh

a=$(~./unit3.2a.sh)
#below is all that don't work!
#instructors: a =~./unit3.2a.sh 2 200
#./unit3.2a.sh "2" "200"
#~./unit3.2a.sh 2 200
#=$(./unit3.2a.sh 2 200)
#=$(./unit3.2a.sh)+(2 200)
#$(./unit3.2a.sh 2 200)
#$(/home/Admin/unit3.2a.sh)
#$(/home/Admin/unit3.2a.sh 2 200)
#added echo $a to see if I wasnt seeing  anything the echo text works fine but a variable does not read?
#set a='./unit3.2a.sh 2 200'
##set a=$(cat ./unit3.2a.sh 2 200)
#$ ./unit3.sh
#cat: 2: No such file or directory
#cat: 200: No such file or directory
#set a=$(~./unit3.2a.sh 2 200)
#a=$(~./unit3.2a.sh 2 200)



echo $a

echo "The result is: $a"

echo "Storing the results.............."

echo "Storing the result: $a" >> unit3.txt

echo "The script is over"

'''

解决方法

请注意：

example_list = [ ['a','b','c'],['f','g','h'],['i','j','k'],] my_string = '' for s in example_list: if example_list[-1] == s: my_string += str(tuple(s))+';' else: my_string += str(tuple(s))+',\n' print(my_string) 指的是特定的文件位置 ~./unit3.2a.sh引用当前目录中的文件

./unit3.2a.sh格式是bash特定的，在C shell中不起作用，请参见

$( command )

产生以下内容的

#!/bin/csh

set a = `./unit3.2a.sh 2 2`

echo $a
echo "The result is: $a"
echo "Storing the results.............."
echo "Storing the result: $a" >> unit3.txt
echo "The script is over"
