Why can't I use Unix Nohup with Bash For-loop?
提问by neversaint
For example this line fails:
例如这一行失败：
$ nohup for i in mydir/*.fasta; do ./myscript.sh "$i"; done > output.txt&
-bash: syntax error near unexpected token `do
What's the right way to do it?
正确的做法是什么？

Because 'nohup' expects a single-word command and its arguments - not a shell loop construct. You'd have to use:
因为 'nohup' 需要一个单字命令及其参数 - 而不是 shell 循环结构。你必须使用：
nohup sh -c 'for i in mydir/*.fasta; do ./myscript.sh "$i"; done >output.txt' &

You can do it on one line, but you might want to do it tomorrow too.
您可以在一条线上完成，但您可能明天也想这样做。
$ cat loopy.sh
#!/bin/sh
# a line of text describing what this task does
for i in mydir/*.fast ; do
./myscript.sh "$i"
done > output.txt
$ chmod +x loopy.sh
$ nohup loopy.sh &

For me, Jonathan's solution does not redirect correctly to output.txt. This one works better:
对我来说，乔纳森的解决方案没有正确重定向到 output.txt。这个效果更好：
nohup bash -c 'for i in mydir/*.fasta; do ./myscript.sh "$i"; done' > output.txt &
nohup bash -c 'for i in mydir/*.fasta; do ./myscript.sh "$i"; done' > output.txt &
