I'm not quite sure I understand. Are you trying to print the first column of the first entry whose third and fourth columns are 00:00:01 and acroread, respectively?

Edit: To add to RudiC's answer:
Code:
echo " 3214 ?        00:00:01 acroread" | grep -Eo "[[:space:]][[:digit:]]{4}[[:space:]]" | tr -d ' '

LaTeXML::Token(3pm)					User Contributed Perl Documentation				       LaTeXML::Token(3pm)

NAME
"LaTeXML::Token" - representation of a token, and "LaTeXML::Tokens", representing lists of tokens. DESCRIPTION
This module defines Tokens ("LaTeXML::Token", "LaTeXML::Tokens") that get created during tokenization and expansion. A "LaTeXML::Token" represents a TeX token which is a pair of a character or string and a category code. A "LaTeXML::Tokens" is a list of tokens (and also implements the API of a LaTeXML::Mouth so that tokens can be read from a list). Common methods The following methods apply to all objects. "@tokens = $object->unlist;" Return a list of the tokens making up this $object. "$string = $object->toString;" Return a string representing $object. Token methods The following methods are specific to "LaTeXML::Token". "$string = $token->getCSName;" Return the string or character part of the $token; for the special category codes, returns the standard string (eg. "T_BEGIN-"getCSName> returns "{"). "$string = $token->getString;" Return the string or character part of the $token. "$code = $token->getCharcode;" Return the character code of the character part of the $token, or 256 if it is a control sequence. "$code = $token->getCatcode;" Return the catcode of the $token. Tokens methods The following methods are specific to "LaTeXML::Tokens". "$tokenscopy = $tokens->clone;" Return a shallow copy of the $tokens. This is useful before reading from a "LaTeXML::Tokens". "$token = $tokens->readToken;" Returns (and remove) the next token from $tokens. This is part of the public API of LaTeXML::Mouth so that a "LaTeXML::Tokens" can serve as a LaTeXML::Mouth. AUTHOR
