问题
I was just trying the below code and it is not working.. please suggest to correct this code..
echo abc.txt | while read name; do find . -name $name; done
output success : ./rak/abc.txt
echo 'abc.txt pqr.txt' | while read name; do find . -name $name; done
output error : find: 0652-009 There is a missing conjunction
echo "abc.txt pqr.txt" | while read name; do find . -name $name; done
output error : find: 0652-009 There is a missing conjunction
same error with
echo "abc.txt" "pqr.txt" | while read name; do find . -name $name; done
echo 'abc.txt' 'pqr.txt' | while read name; do find . -name $name; done
Please suggest how to resolve this problem...
回答1:
The problem is that the multiple entries are sent into the pipe as one line, the read picks up both strings into name and then processes the $name containing the two strings.
You should use something like:
echo -e "abc.txt\npqr.txt" | while read name; do find . -name $name; done
i.e. separate the items with a newline.
You should have tried debugging this by using echo "'$name'" instead of the find and it would have hinted what was happening.
Additionally, I would use quoting around the use of $name in the find, as if the filename is expected to have a space in it's name then you will get the same error message as you have experienced originally.
