What If I Just Want To See The
HTTP Header?
@cptntommy

curl -I
Modifier - Just The HTTP
Header!

curl -I https://bluearray.co.uk

curl -I -L

curl -I -L https://bluearray.co.uk

curl-O

Here we have used CURL TO:
Download Files,
Check HTML,
Check HTTP Header &
Follow Redirects

Sort ‘sorts’

Navigate to Folder and use ‘ls - “list”’
command to make sure the data is
there

Then run the sort command

filename.csvsort

“sort keyworddata.csv”

sort filename > newfilename

Did It Work?

WTF is Head/Tail?

‘Head’ views the first 10 Rows
‘Tail’ views the last 10 Rows

head filename.csv

head filename

sort filename.csv >
Z-A_SortedData.csv

sort filename.csv >
Z-A_SortedData.csv
-r

We want to sort by the
second column

sort -k2 -t,

sort -k2 -t, -n

sort -k2 -t, -n -r

sort -k2 -t, -n -r filename.csv

sort -k2 -t, -n -r filename.csv >
volumesorteddata.csv

head volumesorteddata.csv >
top10KW.csv

head -n100
volumesorteddata.csv >
top100KW.csv

Here sort has been used to:
Sort by Number,
Sort by A-Z,
Sort by Z-A

We have also used head/tail to;
Extract the top 10,
Top 100
Save these to a file

cat - short for “concatenate”

Used to display, combine &
create files

cat *.csv

cat *.csv > alldata.csv

>
User/Desktop/DataToCombine

Short for "stream editor",
allows you to filter and
transform text.

Adding text to rows

Use sed to add protocol &
domain at start of each line

sed -e
's/^/http://www.domain
.com/' file.csv

sed -e 's/^/

sed -e
's/^/http://www.domain.co
m/'

sed -e
.com/'

sed -e
.com/' file.csv > full.csv

use sed to find & replace

Replace http with https

sed -e 's/http file.csv
> newfile.csv
/https/'

Here we have:
Added in protocol & domain
Replaced http with https

Programming language,
used to process text

Following example is one of
the easier applications of
awk

awk -F “,”

awk -F “,”‘{print $1 “,” $2}’

awk -F “,”‘{print $1 “,” $2}’ kw.csv
> betterkw.csv

awk -F “,”‘{print $1 “,” $2 “,” $4}’

How to
combine
all this?

@cptntommy
About 1%
of given
Log Files

@cptntommy
1.cat
Combine
files
together

@cptntommy
Cat *.log > combinedlogs.log

@cptntommy
2. Use sed to add in full domain
name to log file

@cptntommy
sed -e 's //
file.log > newfile.log
/domain.com/'

@cptntommy
sed -e 's //
Forward Slash

@cptntommy
sed -e 's // /domain.com/'
Text to replace with

@cptntommy
sed -e 's //
file.log > newfile.log
/domain.com/'
Then the files

@cptntommy
3.Extract 404 errors
(awk)

@cptntommy
awk '/404/ {print $0}'
combinedlogs.log > log404.log

@cptntommy
4.Extract any
specific
status code
(awk)

@cptntommy
awk '/301/ {print $0}' file.log >
newfile.log

@cptntommy
newfile.log

@cptntommy
5. Extract all
Googlebot/
Mobile Bot
hits (awk)

@cptntommy
awk '/Googlebot/ {print $0}'
all.log > gbot.log

@cptntommy
What if you wanted to know
how many hits each bot had,
without opening the file?

@cptntommy
6. Extract all hits of a specific
URL, or all img requests, all css
requests, all with modification of
1 command

@cptntommy
Replace ‘Googlebot’ with
‘BingBot’, ‘anybot’...

@cptntommy
awk '/Bingbot/ {print $0}' all.log >
gbot.log

@cptntommy
awk '/anybot/ {print $0}' all.log >
gbot.log

@cptntommy
awk '/.css/ {print $0}' all.log >
gbot.log

@cptntommy
awk '/.jpeg/ {print $0}' all.log >
gbot.log

@cptntommy
awk '/whatever-you-want/ {print
$0}' all.log > file.log

@cptntommy
This Barely
Scratches
the
Surface

Extract columns
of data
