Thread: Difference between awk and sed scripting

Hi everyone. I am new in programming word. I cannot know about the awk and sed. I can also not know the differences between the awk and sed. So, I want to know about the awk and sed and also want to know about the Differences between the awk and sed. Any suggestion would e highly appreciated. Thanks in advanced

The following can be some of the differences between the awk and sed as:

1. The awk is also used as a "parse XML files or text files to execute SQL commands from the data extracted.

2. The awk used for difficult calculations and formatting raw data to statistical tables.

3. The SED, Flat screen technology;

4. The SED, A Self Extraction Directive file is essential for the creation of a cabinet (. CAB) using Microsoft IExpress.

awk and sed both invented in UNIX.

At the highest level of description,

awk is a tokenize.
sed is an automated editor (stream editor).


Examples:

Code:

awk '{ print $2 }' "51 52 53"
Prints "52" - extract the second token/field.

sed 's/52/XX/' "51 52 53"
Prints "51 XX 53" - substitutes (s) 52 with XX

In windows, I use biterscripting to do similar things. related examples.

wex "2" "51 52 53"
Prints "52" - extract the second token/field. wex = word extractor

sal "^52^" "XX" "51 52 53"
Prints "51 XX 53" - substitutes (s) 52 with XX. sal = string alerter
