[问题] 直接调用通过，放到脚本里就报错的两个命令[已解决]

5451vs5451 · #1

下面两条命令在终端下运行一点问题没有，一放到脚本里就出错。

命令一：

代码：全选

test $PWD = @(/home/ubuntu/documents|$my_doc_base) || exit 1

错误信息：

代码：全选

/home/ubuntu/.gnome2/nautilus-scripts/InstallDocument: line 55: syntax error near unexpected token `('
/home/ubuntu/.gnome2/nautilus-scripts/InstallDocument: line 55: `test ! $PWD = (/home/jianghua/documents|$my_doc_base) || exit 1'

命令二：

代码：全选

temp=$(ls -d [Hh][Tt][Mm]?(L|l)/* * 2>/dev/null | 
    grep -i -m 1 '^\(.*/\)\?index\.html\?\(\.gz\)\?$') ||
temp=$(ls -d [Hh][Tt][Mm]?(L|l)/* * 2>/dev/null | 
    grep -i -m 1 '\.html\?\(\.gz\)\?$')

错误信息：

代码：全选

/home/ubuntu/.gnome2/nautilus-scripts/InstallDocument: command substitution: line 34: syntax error near unexpected token `('
/home/ubuntu/.gnome2/nautilus-scripts/InstallDocument: command substitution: line 34: `ls -d [Hh][Tt][Mm]?(L|l)/* * 2>/dev/null | '
/home/ubuntu/.gnome2/nautilus-scripts/InstallDocument: command substitution: line 36: syntax error near unexpected token `('
/home/ubuntu/.gnome2/nautilus-scripts/InstallDocument: command substitution: line 36: `ls -d [Hh][Tt][Mm]?(L|l)/* * 2>/dev/null | '

把命令中的?(L|l)去掉后可以运行，但命令功能就变了。

原来是extglob选项没打开，先用shopt -s extglob开启，然后在运行就能通过了。

代码：全选

If  the  extglob shell option is enabled using the shopt builtin, several extended pattern
       matching operators are recognized.  In the following description, a pattern-list is a list
       of  one  or more patterns separated by a |.  Composite patterns may be formed using one or
       more of the following sub-patterns:

              ?(pattern-list)
                     Matches zero or one occurrence of the given patterns
              *(pattern-list)
                     Matches zero or more occurrences of the given patterns
              +(pattern-list)
                     Matches one or more occurrences of the given patterns
              @(pattern-list)
                     Matches one of the given patterns
              !(pattern-list)
                     Matches anything except one of the given patterns
