Problems with single quotes in a bash script

I have seen this post but my problem is more complicated and simply replacing single quotes with double quotes won't work. I need to run a R CMD BATCH command with single quotes and double quotes within the single quotes, something like this

echo 'R CMD BATCH --no-save '--args "xxx.txt"' xxx.r' | qsub -cwd &

What should I do?

使用here-document，而不是管道，这样就不需要外层的引号。

qsub -cwd <<'EOF' &
R CMD BATCH --no-save '--args "xxx.txt"' xxx.r
EOF

为此，我使用所谓的5 引号模式：

 'this '"'"' that'

=>this ' that

 "this "'"'" that"

=>this " that
