Full Discussion: Pic a value from a line at runtime

You can use "sed" to manipulate the line. The following expression will pick up anything between "BILL" and "ACCOUNT":

Code:
echo "BIP in report_one_acnt> **SUCCESSFUL** BILL 25895519 ACCOUNT 7615" |\
sed 's/^.*BILL //; s/ ACCOUNT.*$//'

The first regexp cuts away everything before and including "BILL " (with a space following), the second cuts everything from " ACCOUNT" (with a leading blank) to the end of line, which leaves solely the number.

Still, this might have to be checked if it is indeed a number (for instance, "...BILL FOOBAR ACCOUNT..." might break whatever follows, because the extracted "FOOBAR" is NOT a number). You can do this by:

Code:
# catch the result in a variable
var="$( echo "BIP in report_one_acnt> **SUCCESSFUL** BILL 25895519 ACCOUNT 7615" |\
        sed 's/^.*BILL //; s/ ACCOUNT.*$//' \
      )

# test if "$var" contains only digits:
if [ -n "$(echo "$var" | sed 's/[0-9]//g)" ] ; then
     echo "$var is not a number"
else
     echo "$var is a number"
fi

I hope this helps.

DESCRIPTION

       mc-tool's usage depends on its first argument (the "command")

   SPECIFYING ACCOUNTS
       Where an account name is needed, it may be given as a full object path (e.g.  /org/freedesktop/Telepathy/Account/gabble/jabber/example), or
       as the unique account-specific suffix (e.g.  gabble/jabber/example).

   SPECIFYING PARAMETER SETTINGS
       Many commands take arguments that represent Telepathy connection manager parameters (see the Telepathy Specification for details of these).
       Each argument has the following form:

       TYPE:NAME=VALUE

       where  TYPE  is either int, uint, bool, or string (other parameter types exist, but are currently unsupported by mc-tool), NAME is the name
       of the connection manager parameter (e.g.  account or password), and VALUE is the parameter's value (with integers in decimal, and booleans
       as 0 or 1).

       The update command also accepts arguments of the form clear:NAME which delete the named parameter from the account configuration.

   LIST
       mc-tool list lists the available accounts.

   ADD
       mc-tool	add  adds  an  account.  The  connection  manager and protocol can either be given as the name of a Mission Control profile, (e.g.
       gtalk), or as a slash-separated connection manager name and protocol (e.g.  gabble/jabber).

   DISPLAY
       mc-tool display ACCOUNT DISPLAY-NAME sets the DisplayName property of ACCOUNT to DISPLAY-NAME.

   NICK
       mc-tool nick ACCOUNT NICKNAME sets the Nickname property of ACCOUNT to NICKNAME.

   SERVICE
       mc-tool service ACCOUNT SERVICE-NAME sets the Service property of ACCOUNT to SERVICE-NAME.

   ICON
       mc-tool icon ACCOUNT ICON sets the Icon property of ACCOUNT to ICON.

   SHOW
       mc-tool show ACCOUNT shows information about ACCOUNT.

   GET
       mc-tool get ACCOUNT PARAMETER [PARAMETER...]  shows the values of the given parameters of ACCOUNT.

   ENABLE
       mc-tool enable ACCOUNT sets the Enabled property of ACCOUNT to True.

   DISABLE
       mc-tool disable ACCOUNT sets the Enabled property of ACCOUNT to False.

   AUTO-PRESENCE
       mc-tool auto-presence ACCOUNT STATUS [MESSAGE] sets the AutomaticPresence property of ACCOUNT to STATUS with optional message MESSAGE.

   REQUEST
       mc-tool request ACCOUNT STATUS [MESSAGE] sets the RequestedPresence property of ACCOUNT to STATUS with optional message	MESSAGE;  this	is
       how you tell an account to connect or go offline, for example.

   AUTO-CONNECT
       mc-tool	auto-connect  ACCOUNT  on  sets the ConnectAutomatically property of ACCOUNT to True.  mc-tool auto-connect ACCOUNT off sets it to
       False.
