  • How to escape single quotes within single quoted strings? 19 answers

    • 你可以使用外部的"代替： 

    echo "truncate 'testTruncate' "|hbase shell

    You can include a ' in a string that is quoted by ' as follows: 

    echo 'O'''Brien'

    or 

    echo 'O'"'"'Brien'

    In both case you will get O'Brien as output. Note that in both case, we there essetially 3 strings, one next to the other, eg 'O' , ' , 'Brien' .

    This looks ugly, but unfortunately backslash escapes are not supported in single quoted strings in bash.
