copied!<p>Does the variable <code>$i</code> contain the value <code>profile$</code>? I'm going to assume that it does.</p> <p>A dollar at the end of the word is tricky. Without the variable, you could write:</p> <pre><code> Bool=$(grep '^profile\$' File1) </code></pre> <p>With the variable, we need a trick to suppress the meaning of <code>$</code> as a metacharacter:</p> <pre><code>Bool=$(grep "^$i.*" File1) </code></pre> <p>(Note that it is far better to use <code>$(...)</code> than the equivalent with back-ticks, aka back-quotes.)</p> <p>Also, of course, if you want the whole line to be exactly <code>profile</code>, then there's no need for special tricks:</p> <pre><code>Bool=$(grep "^$i" File1) </code></pre> <p>should work fine.</p> <hr> <h3>Dealing with the Creature Feep in the Question</h3> <pre><code>while read -r i do Bool=$(grep "^$i.*" File1) if [ -z "$Bool" ] then echo " $i Not Available" fi done < File2 </code></pre> <p>The <code>-r</code> suppresses some expansions that you might otherwise suffer from. If your shell doesn't like it, drop it; you'll usually be OK without it.</p> <hr> <h3>Another way to do it</h3> <p>If you are looking for missing lines and order is not important, then you could sort both <code>File1</code> and <code>File2</code> and then use <a href="http://pubs.opengroup.org/onlinepubs/9699919799/utilities/comm.html" rel="nofollow"><code>comm</code></a> to compare them, getting the entries that are in <code>File2</code> but not in <code>File1</code>. If you've got <code>bash</code> and 'process substitution' available, then:</p> <pre><code>comm -13 <(sort File1) <(sort File2) </code></pre> <p>If you don't have process substitution, then:</p> <pre><code>sort -o File1 File1 sort -o File2 File2 comm -13 File1 File2 </code></pre>
