搜索和使用bash

Question

更換輸出這是我的bash代碼：

paste - - - - - - - < /home/secmgr/attmrms1/data_tripwire1.txt | while read -a values; do 
    mean=$(arith_mean "${values[@]}") 
    sd=$(sd $mean "${values[@]}") 
    echo "${values[@]} $mean $sd" 
    echo "<tr><td>Baseline<td>Standard deviation=$sd<td>"${values[@]} $sd"</tr>" >> $HTML 
    done | column -t 

我所要的輸出是這樣的：

Month CBS  GFS  HR  HR   Payroll INCV 
     cb2db1 gfs2db1 hr2web1 hrm2db1 hrm2db1a incv2svr1 
2013-07 85  76  12  28  26   4 
2013-08 58  103  18  6   24   18 
2013-09 54  110  11  14  25   17 
2013-10 108  129  17  8   23   18 
2013-11 52  137  12  8   21   30 
2013-12 18  84  6  0   13   13 
2014-01 8  16  1  0   9   3 
*Standard 
deviation 
(7mths) 31.172 35.559 5.248 8.935 5.799 8.580 
* Mean 
(7mths) 54.428 94.285 11.142 9.142 20.285 14.714 

我現在面臨的問題是，輸出看起來如下面所示：

Month CBS  GFS  HR  HR   Payroll INCV 
     cb2db1 gfs2db1 hr2web1 hrm2db1 hrm2db1a incv2svr1 
2013-07 85  76  12  28  26   4 
2013-08 58  103  18  6   24   18 
2013-09 54  110  11  14  25   17 
2013-10 108  129  17  8   23   18 
2013-11 52  137  12  8   21   30 
2013-12 18  84  6  0   13   13 
2014-01 8  16  1  0   9   3 
Baseline Standard deviation=31.712 
Baseline Standard deviation=35.559 
Baseline Standard deviation=5.248 
Baseline Standard deviation=8.935 
Baseline Standard deviation=5.799 
Baseline Standard deviation=8.580 

我想Baseline Standard deviation是所有在一個單行，而不是分開。事情是這樣的：

Baseline Standard deviation=31.712 35.559 5.248 8.935 5.799 8.580

這裏有一種方法：

echo "Standard Deviation" 
echo "<tr><td>Standard Deviation</td></tr>" >> $HTML 
echo "<tr>" >> $HTML 
paste - - - - - - - < /home/secmgr/attmrms1/data_tripwire1.txt | while read -a values; do 
    mean=$(arith_mean "${values[@]}") 
    sd=$(sd $mean "${values[@]}") 
    printf "%s " $sd 
    echo "<td>$sd</td>" >> $HTML 
    done | column -t 
printf "\n"; 
echo "</tr>" >> $HTML 

echo "Mean" 
echo "<tr><td>Mean</td></tr>" >> $HTML 
echo "<tr>" >> $HTML 
paste - - - - - - - < /home/secmgr/attmrms1/data_tripwire1.txt | while read -a values; do 
    mean=$(arith_mean "${values[@]}") 
    printf "%s " $mean 
    echo "<td>$mean</td>" >> $HTML 
    done | column -t 
printf "\n"; 
echo "</tr>" >> $HTML
