    <p>I have next awk oneliner :</p> <pre><code>{dict[$2"@"$6]=($(NF-2)/($(NF-2)+$NF))*100 } END {for (a in dict) { printf "%s %d :" , a, int(dict[a]) }} </code></pre> <p>What i need, is to add to value of each dictionary key combination of </p> <pre><code>($(NF-2)/($(NF-2)+$NF))*100 " out of" $(NF-2)+$NF </code></pre> <p>So i want awk to calculate all math , then compose string and put it as dictionary value. I already tried with some combination of spaces and brackets but still no luck. </p> <p>Vars are filled from input stream :</p> <pre><code>$2 - host , not unique in input stream $3 - partition , not unique in input stream $NF - space avail $NF-2 - space used $(NF-2)+$NF - gives you overall capacity of partiton </code></pre> <p>Output is </p> <pre><code>80% host1@/local/1 </code></pre> <p>Output expected:</p> <pre><code>80% host1@/local/1 out of 112G </code></pre> <p>----------------------Solution-----------------------------------</p> <p>With good catch below , i resolved this. Issue was that i did int() in printf part, that truncated output. Though, further i faced other problems with my wrap-around shell part, therefore my final code was different than i expected it to be asking question.</p> <pre><code>'{key=($2 "@" $6 " out of " int((($(NF-2)+$NF)/1000)/1000) "GB" ) ; dict[key]=($(NF-2)/($(NF-2)+$NF))*100 } END {for (a in dict) { printf "%s , %d :" , a, int(dict[a]) }}' </code></pre> <p>I`ve moved "out of " and capacity part to dictionary key , because dict value cannot be string in my case, futher i will compare it with INT.</p>

    1. COI`ve added details, but they have low importance in scope of my question. Question is, how to concat (as sting) result of math + string + result of math, to place it into the dictionary . I start to think that awk have problem with this.

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.
