Parsing in Linux shell script - linux

Question

I am trying to parse the output below:
+--------------------------------------+-----------------+-----------+------+-----------+------+-------+-------------+-----------+
| ID | Name | Memory_MB | Disk | Ephemeral | Swap | VCPUs | RXTX_Factor | Is_Public |
+--------------------------------------+-----------------+-----------+------+-----------+------+-------+-------------+-----------+
| 1 | m1.tiny | 512 | 1 | 0 | | 1 | 1.0 | True |
| 2 | m1.small | 2048 | 20 | 0 | | 1 | 1.0 | True |
| 214b272c-e6a4-4bb5-96a4-c74c64984e5a | MC | 2048 | 100 | 0 | | 1 | 1.0 | True |
| 3 | m1.medium | 4096 | 40 | 0 | | 2 | 1.0 | True |
| 4 | m1.large | 8192 | 80 | 0 | | 4 | 1.0 | True |
| 5 | m1.xlarge | 16384 | 160 | 0 | | 8 | 1.0 | True |
| 71aa57d1-52e3-4499-abd2-23985949aeb4 | slmc | 4096 | 32 | 0 | | 2 | 1.0 | True |
| 7cf1d926-c904-47b8-af70-499196a1f65f | new test flavor | 1 | 1 | 0 | | 1 | 1.0 | True |
| 97b3dc38-f752-437b-881d-c3415c8a682c | slstore | 10240 | 32 | 0 | | 4 | 1.0 | True |
+--------------------------------------+-----------------+-----------+------+-----------+------+-------+-------------+-----------+
It is the list of flavours in open-stack. I am expecting output as below:
m1.tiny;m1.small;MC;m1.medium;m1.large;m1.xlarge;slmc;new test flavor;slstore;
What I tried:
I came up with below command for parsing:
nova flavor-list | grep '|' | awk 'NR>1 {print $4}' | tr '\n' ';'
but the issue is that the command returns output as follows:
m1.tiny;m1.small;MC;m1.medium;m1.large;m1.xlarge;slmc;new;slstore;
There is a problem with the space in new test flavor.

Answer 1

Below command will give expected output
nova flavor-list | grep '|' | awk -F "|" 'NR>1 {print $3}' | tr '\n' ';'
Above command will give output will white spaces i.e.
$ nova flavor-list | grep '|' | awk -F "|" 'NR>1 {print $3}' | tr '\n' ';'
m1.tiny ; m1.small ; MC ; m1.medium ; m1.large ; m1.xlarge ; slmc ; new test flavor ; slstore ;
To get output without white spaces use below command
$nova flavor-list | grep '|' | awk -F "|" 'NR>1 {print $3}' | awk -F "\n" '{gsub(/^[ \t]+|[ \t]+$/, "", $1)}1' | tr '\n' ';'
m1.tiny;m1.small;MC;m1.medium;m1.large;m1.xlarge;slmc;new test flavor;slstore;

Answer 2

Use the following command
sed -e '1,3d' < flavor-list | sed -e 's/-//g' | sed -e 's/+//g' | cut -f 3 -d "|" | sed -e 's/^ //g' | sed -e 's/\s\+$//g' | tr '\n' ';'

Answer 3

Software tools (no sed, no awk):
tail -n +4 flavor-list | grep -v '\-\-' | cut -d'|' -f3 | cut -d' ' -f2- | \
tr -s ' ' | rev | cut -d' ' -f2- | rev | tr '\n' ';' ; echo
Pure bash (uses no utils at all):
while read a b c d ; do \
d="${d/ [ |]*/}" ; \
[ -z "$d" -o "$d" = Name ] && continue ; \
echo -n "$d;" ; \
done < flavor-list ; echo
Output (either one):
m1.tiny;m1.small;MC;m1.medium;m1.large;m1.xlarge;slmc;new test flavor;slstore;
