问题描述

我需要使用执行/同时执行"循环读取文件.
如何以字符串形式读取内容?

I need to read a file using a "Do/While" loop.
How can I read the contents as a string?

这是我的代码:

cat directory/scripts/tv2dbarray.txt | while read line
do
  echo "a line: $line"
done

错误:

test.sh: line 4: syntax error near unexpected token `done'
test.sh: line 4: `done'

推荐答案

cat file | while read line
do
  echo "a line: $line"
done

要将文件内容放入var中，请使用:

To get file contents into a var use:

foo="`cat file`"
