[英]I'm having trouble writing a “For Loop” statement that checks a text file to see if each exist in it
I'm writing a "for loo" statement that checks a test file to see if the mutiple entered arguments exists. 我正在编写一个“for loo”语句,用于检查测试文件以查看是否存在多个输入的参数。 The script I have written just returns the everything as if it exists even if it doesn't 我编写的脚本只返回所有内容,就好像它存在一样,即使它不存在
for i in "$@"
do
grep -q "$i" /home/s132a18/A10/cisStudents && echo "$i is a student" || echo "$i is not a student"
done
When the word not
is the only difference: 当单词not
唯一的区别时:
for i in "$@"
do
echo "$i is $(grep -q "$i" /home/s132a18/A10/cisStudents || echo "not ")a student"
done
