RE: parse a file and fill an array with it
Hi Franklin,

Thanks you, I got it working.
But, I want these details in a array with extra spaces removed.

However, I tried by adding a ssh command to it and does not work
When I do this the loop gets restricted to a single iteration. ?I did not see the second iteration happening. and it happens only the case of ssh.

Instead local commands works fine.

awk '{for(i=2;i<=NF;i++){print $i}}' "a" |
while read mach; do
#do your stuff here
echo "hello $mach"
ssh root@rna4 uname -n # <----
echo $?
done

Regards,
Mukund Jampala

while read mach; do
  #do your stuff here
  echo "$mach"
done

xmstringtableparsestringarray

XmStringTableParseStringArray(library call)							       XmStringTableParseStringArray(library call)

NAME

       XmStringTableParseStringArray -- A convenience function that converts an array of strings to a compound string table

SYNOPSIS

       #include <Xm/Xm.h>
       XmStringTable XmStringTableParseStringArray(
       XtPointer *strings,
       Cardinal count,
       XmStringTag tag,
       XmTextType type,
       XmParseTable parse,
       Cardinal parse_count,
       XtPointer call_data);

DESCRIPTION

       XmStringTableParseStringArray  takes an array of strings, allocates an XmStringTable with an equal number of slots, calls XmStringParseText
       on each string in strings, and inserts the resulting XmString in the corresponding slot in the XmStringTable.

       strings	 Specifies an array of strings of characters as determined by type.

       count	 Specifies the number of strings in strings.

       tag	 Specifies the tag to be used in creating the result. The type of tag created (charset or locale) depends on the type of the  text
		 and  the  value given. If the value specified is NULL, and type indicates that a charset tag should be created, then the tag will
		 have  the  value  of  XmFONTLIST_DEFAULT_TAG.	 If  type  indicates  a  locale  tag,  then  the  tag  will  have  the	value	of
		 XmFONTLIST_DEFAULT_TAG.

       type	 Specifies  the  type  of  text  to be passed in and the type of tag. If the type is either XmMULTIBYTE_TEXT or XmWIDECHAR_TEXT, a
		 locale tag should be created. If the type is XmCHARSET_TEXT, a charset tag will be created.

       parse	 Specifies the parse table to be used.

       parse_count
		 Specifies the number of entries in the parse table.

       call_data Specifies data to be passed to the parse procedures.

RETURN

       Returns a new XmStringTable.  The function allocates space to hold the XmStringTable.  When the application no longer  needs  the  returned
       XmStringTable,  the  application  should  call XmStringFree count times (that is, one time for each returned compound string) and then call
       XtFree to deallocate the XmStringTable itself.

RELATED

       XmStringFree(3) and XmTabList(3).
