copied!<p>Two join every pair of adjacent lines just pipe your output to <code>awk 'NR%2{line=$0;next}{print line sep $0}' sep=" >> "</code> adjusting <code>sep</code> to your need.</p> <p><strong>Addendum:</strong></p> <p>In response to the original author's comment I am going to explain some details of this solution:</p> <p><code>awk</code> processes input record-wise, without further options that is line-by-line. The (internal) variable <code>NR</code> stores the current record's number. <code>%</code> is the modulus operator, so <code>NR%2</code> evaluates to <code>1</code> for odd line numbers and <code>0</code> for even line numbers. <code>{...}</code> groups commands (so called 'action') to perform. Since <code>1</code> is considered "true" and <code>0</code> "false" the first action is only performed for odd line numbers. This action consists of two commands: First, the whole line (<code>$0</code>) is stored in the variable <code>line</code> and then the <code>next</code> record is processed (without considering any other action). For even lines, this action is not performed, so the second action is considered. Since there is no expression before the <code>{</code> the action is performed: the stored (i.e. previous) <code>line</code> is concatenated with a variable called <code>sep</code> and the current line (<code>$0</code>). The resulting string is printed (and automatically appended by <em>one</em> new-line in the end). The value of <code>sep</code> is handed to <code>awk</code> as a parameter to make it easy to adjust it without messing with the script. Since <code>awk</code> reads standard input and output without further arguments you can just pipe (<code>|</code>) the output of your find to <code>awk</code> (<code>find ... -exec ... -exec ... | awk ... > ...</code>)</p>
