arch是个什么命令？

molucule

在装pgi7.0.5时遇到的：
type arch > /dev/null 2>&1
if test $? -ne 0 ; then
  echo
  echo "ERROR: arch not found (PATH = \$PATH)"
  quit
fi

我用的是debian，到这里就退出了，另外，type是什么啊？

不管是什么命令，已经采取措施跳过去了，能正常安装了。

虽然迟到了, 但对于以后来看帖子的人也许还有用

2. $ type type
   
3. type is a shell builtin
   
4. $ help type
   
5. type: type [-afptP] name [name ...]
   
6.     For each NAME, indicate how it would be interpreted if used as a
   
7.     command name.
   
8. 
   
9.     If the -t option is used, `type' outputs a single word which is one of
   
10.     `alias', `keyword', `function', `builtin', `file' or `', if NAME is an
    
11.     alias, shell reserved word, shell function, shell builtin, disk file,
    
12.     or unfound, respectively.
    
13. 
    
14.     If the -p flag is used, `type' either returns the name of the disk
    
15.     file that would be executed, or nothing if `type -t NAME' would not
    
16.     return `file'.
    
17. 
    
18.     If the -a flag is used, `type' displays all of the places that contain
    
19.     an executable named `file'.  This includes aliases, builtins, and
    
20.     functions, if and only if the -p flag is not also used.
    
21. 
    
22.     The -f flag suppresses shell function lookup.
    
23. 
    
24.     The -P flag forces a PATH search for each NAME, even if it is an alias,
    
25.     builtin, or function, and returns the name of the disk file that would
    
26.     be executed.
    
27. typeset: typeset [-afFirtx] [-p] name[=value] ...
    
28.     Obsolete.  See `declare'.

arch 等同于 uname -m, 而 type 是查看一个命令的类型的. 在楼主的例子中, 就是检测 arch 命令是否存在于 PATH 中

arch属于哪个软件包？
我在debian下找不到这个软件或命令。

remote fish

真遗憾, 我也是在单位的 FC4 上找到它的

alpha.gu

arch是查看机器体系结构的，就是386，486这种。
