shell script to capture string from a table - bash

I am writing a shell script to upload a file to a specific folder on google drive. I have started out on the terminal though, to see how it can be done.
$ now=$(date +"%Y")
$ echo now
2015
$ drive list | grep -w $now

The first column is the file/folder id, second column is the file/folder name from my google drive.
I need to look for a folder by the name yyyy (current year). And then retrieve its id. If the folder does not exist then I have to create one.
I am currently using the gdrive on Ubuntu 14.04.2.
How do I get the desired file id from the above table?

This worked for me-
drive list | grep -w " 2015 " | grep -Eo '^[^ ]+'

Bash sed awk, format CPU/Mem info from /proc/cpuinfo and /proc/meminfo [closed]

The problem that I'm trying to solve is to produce portable output that I can display on all of the servers in our environment to show basic info at login using generic information on all CentOS / Red Hat systems. I would like to pluck info from /proc/cpuinfo and /proc/meminfo (or free -m -h); "why not just 'yum install some-great-tool'?" is not ideal as all of this information is freely available to us right in /proc. I know that this sort of thing can often be a very simple trick for sed/awk experts (I don't know how to approach this
with my limited sed/awk knowledge).
I would like to extract something like the following on a single line:
<model name>, <cpu MHz> MHz, <cpu cores> cores, <detect "vmx" (Intel-VT) or "svm" (AMD-V support)>
e.g. with the below output, this would look like (with "1300.000" rounded to "1300")
"AMD Athlon(tm) II Neo N36L Dual-Core Processor, 1300 MHz, 2 cores, VMX-Virtualization" (or "SVM-Virtualization" or "No Virtualization")
I would like to also combine this info with that of /proc/meminfo or free -mh, so:
"AMD Athlon(tm) II Neo N36L Dual-Core Processor, 1300 MHz, 2 cores, 4.7 GB Memory (1.8 GB Free), SVM-Virtualization"
I have spent some time searching for methods, but without luck, and maybe this is an interesting generic problem as involves taking the format of tables that a lot of info is held in and extracting as required so has some generic application.

Using /proc/cpuinfo and free -mh along with awk, search for the strings required, using : as the field delimited, set variables accordingly, splitting the output of free -mh further into an array called arr based on " " as the delimiter. At the end, print the data in the required format using the variables created.
When searching for lines beginning with flag, we search for strings svn or vmx using awk's match function. A match will signified by the RSTART variable not being 0 and so we check this to find the type of virtualisatiion being utilised. As we have set virt to No Virtualisation at the beginning, no matches will print No Virtualisation.
awk -F: '/^model name/ {
mod=$2
}
/^cpu MHz/ {
mhz=$2
}
/^cpu core/ {
core=$2
}
/^flags/ {
virt="No Virtualisation";
match($0,"svm");
if (RSTART!=0)
{
virt="SVM-Virtualisation"
};
match($0,"vmx");
if (RSTART!=0) {
virt="VMX-Virtualisation"
}
}
/^Mem:/ {
split($2,arr," ");
tot=arr[1];
free=arr[2]
}
END {
printf "%s %dMHz %s core(s) %s %sB Memory (%sB Free)\n",mod,mhz,core,virt,tot,free
}' /proc/cpuinfo <(free -mh)
One liner:
awk -F: '/^model name/ { mod=$2 } /^cpu MHz/ { mhz=$2 } /^cpu core/ {core=$2} /^flags/ { virt="No Virtualisation";match($0,"svm");if (RSTART!=0) { virt="SVM-Virtualisation" };match($0,"vmx");if (RSTART!=0) { virt="VMX-Virtualisation" } } /^Mem:/ {split($2,arr," ");tot=arr[1];free=arr[2]} END { printf "%s %dMHz %s core(s) %s %sB Memory (%sB Free)\n",mod,mhz,core,virt,tot,free }' /proc/cpuinfo <(free -mh)

According to the output, result of Active(file) + Inactive(file) + Shmem doesn't equal to that of Cached + Buffer + SwapCached
Active — The total amount of buffer or page cache memory, in kilobytes, that is in active use. This is memory that has been recently used and is usually not reclaimed for other purposes.
Inactive — The total amount of buffer or page cache memory, in kilobytes, that are free and and available. This is memory that has not been recently used and can be reclaimed for other purposes.
Ref : https://www.centos.org/docs/5/html/5.1/Deployment_Guide/s2-proc-meminfo.html
And FYI.
Active = Active(anon) + Active(file) Inactive = Inactive(anon) + Inactive(file)
Active(file), Inactive(file) has file back-end which means its original file is in disk but to use it faster it was loaded on RAM.
Active(file) + Inactive(file) + Shmem = Cached + Buffer + SwapCached

How can I sort by the 4th and then 3rd column so that it's sorted by file size?
I've tried :%!sort -k4 -k3n which partially works, but seems to fail on the 3rd size column.
What am I doing wrong?
I think I've figured it out.
:%!sort -k4 -bk3g
I sort by the the 4th column (-k4), followed by the 3rd column. We ignore leading blank spaces (b), and this time we sort using a general numeric sort (g).
I blogged about this too
I don't know how to handle it with sort(). I've found problems with the decimal point, although I changed the LC_NUMERIC environment variable, so I would switch to perl to solve it, like:
:%!perl -0777 -ne '
#l = map { [ $_, split " ", $_ ] } split /\n/, $_;
#l = sort { $a->[-1] cmp $b->[-1] or $a->[-2] <=> $b->[-2] } #l;
print "$_->[0]\n" for #l
'
Put it in the same line to run if from inside vim. It yields:

I got a formula to calculate the Memtotal:
Memtotal = MemFree + Cached + Active + Inactive + Mapped + Shmem + Slab + PageTables + VmallocUsed
but I don't know the formula is correct or not, any one can help to clarify it?
I think it would be difficult to reach to the exact value (addition based total memory validation) from meminfo.
Nonetheless, in my view following should lead you close to TotalMemory figure.
TotalMemory = MemFree + Buffers + Cached + Dirty + AnonPages + Slab + VmAllocUsed
In your example case
1432728 + 16568 + 324864 + 60 + 222868 + 24268 + 13916 = 2035272

(From another stackoverflow article suggested above)
Apart from that, I believe the volatility is because of VmAllocUsed.
