Bash 脚本 - 在 for 循环中使用 if

Question

I am total noob in bash scripting and do not know what the problem is within my code; I am writing an sh extension file that will be used as a buffer into the Linux sys. This is just a practice but I do not know what the problem within the code really is, can someone tell me?

Thanks

This is the answer I came up with in the end

#!/bin/bash
>oldFiles.txt
files=$(grep ' jane ' ../data/list.txt | cut -d ' ' -f 3)
for x in $files;
do 
    if test -e ../data/$x; then echo $x >> oldFiles.txt; else echo $x; fi;
done
