    <p>I have this code</p> <pre><code>week=`date +%V_%d` date=`date +%d%m%y` #Cat to a file let tamano=`cat Prenum` file="White_prepago_${date}.txt" name="base_prepago_paqu_w$week_" cat WhiteList.txt | grep ",0" | sed '/^57/!s/^/57/' | awk '{FS=","}{print $1}'&gt; $file # the number of lines of the file let numlines=$2 #Must begin in the line in the file let lines=$tamano+$2 num=$3 for ((i=1; i&lt;=$num; i++)) do let d=$4+$i cat $file | head -$lines | tail -$numlines &gt; base_$d let lines=$lines+$numlines done let lines=$lines-$numlines echo $lines&gt;Prenum </code></pre> <p>I am executing this code in a VM with Linux and works, and now i am intenting run this code in a Solaris Machine but not works, In solaris the file run but not works fine because create the number of files that i write but all my files are the seim, and in linux create all my files but with the increment. The code have to split a file in the lines that i write</p> <p>for example</p> <pre><code> bash script.sh 5000 3 0 </code></pre> <p>This code create 3 files of 5000 lines since base_1 from the file: base_prepago_paqu_w$week_". I am not using split because i need read the number in the file Prenum or Posnum.</p> <p>In the file Prenum there is a number </p> <pre><code>$cat Prenum 5008971 </code></pre> <p>And the code select a range of the file for example if the number is: 5008971 and i write <code>bash script.sh 5000 3 0</code> the output are 3 files from the line 5008971+5000 to 5008971+15000.</p> <p>Could you please help me with my problem?, or with other idea that works in solaris?</p>

    2. COWhy do you sum the 4th argument $4 (in your example `bash script.sh 5000 3 0` it is NULL) and the $i to obtain the "d" value?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
