Need to append matching strings in a file

Shell Programming and Scripting

Hi ,

I am writing a shell script to check pvsizes in linux box.

[root@pavan san_migration]#  for i in `cat vgs1`
> do
> echo "########### $i ###########"
> pvs|grep -i $i|awk '{print $2,$1,$5}'>pvs_$i
> pvs|grep -i $i|awk '{print $1}'|while read a
> do
> fdisk -l $a|head -2|tail -1|awk '{print $2,$3}'>pvs_$i1
> done
> cat pvs_$i
> cat pvs_$i1
> done
########### system ###########
system /dev/sda2 39.41g
/dev/sda2: 42.3
[root@pavan san_migration]#

Now i want to merge the output of last lines into single line like below through shell script

system /dev/sda2 39.41g 42.3

can some one help with it.

Just change print to printf in first awk as highlighted above.

replace the file cats with the funky code below ...

cat pvs_$i pvs_$i1 | tr "\n" "\c" | awk -F"[ c]" '{print $1, $2, $3, $5}'
