Shell script to append text to each file?
提问by Steve
I have a folder full of text files. I need to append the same block of text to each of them (and of course overwrite the original file).
我有一个装满文本文件的文件夹。我需要将相同的文本块附加到每个文件中（当然还需要覆盖原始文件）。
I was wondering what the correct Bash shell syntax would be for this. Would I use cat?
我想知道正确的 Bash shell 语法是什么。我会用猫吗？
I have done a few batch scripts but I'm not a Bash expert. Any suggestions appreciated.
我已经完成了一些批处理脚本，但我不是 Bash 专家。任何建议表示赞赏。

Use append redirection.
使用附加重定向。
for f in *.txt
do
cat footer >> "$f"
done
回答by GreenMatt
If you're needing to do this via a script, you can use echo and append redirection to get the extra text into the files.
如果您需要通过脚本执行此操作，您可以使用 echo 和 append 重定向将额外的文本放入文件中。
FILES=pathto/*
for f in $FILES ; do
echo "#extra text" >> $f
done
