Displaying a Substring with awk
Substring extraction can be performed using a built-in function of awk. The function has the following form:
substr(string,position of first character of substring,substring character count)
The following example extracts a substring of three characters from the third field of the VAR variable, starting from the second character in the field.
echo $VAR | awk '{print substr($3,2,3)}'
You get the following output:

Displaying a Substring with expr
Here is a method of extracting a substring using expr. It uses the substr() function of expr. As before, the first argument is the string, the second is the position of the desired substring s starting character, and the last is the number of characters in the substring. The example gets 4 characters from the string stored in VAR, starting at character number 12.
(expr substr "$VAR" 12 4)
The following output results:
rown
Conducting Simple Search and Replace with sed
The following example searches for space characters within each line of input and replaces them with the string %20. The search-and-replace syntax follows the pattern s/search string/replacement string/. The g at the end of the expression is optional; it stands for global and indicates that you want to replace all instances of the search term found in the line. Without the g, the command replaces only the first instance of the search term.
echo $VAR | sed -e "s/ /%20/g"
The following output results:
The%20quick%20brown%20fox%20jumped%20over%20the%20lazy%20dog.
Disregarding Blank and Commented Lines from a File
This example is a little more involved. First it uses a sed command to filter all lines that have been commented out in a specified file (here, /etc/ntp.conf). The output is then piped to awk, which is used to print only non-null lines (i.e., lines whose length is not 0). The sed command checks whether each line starts with a pound sign (#) and is followed by a string that matches the pattern .*, which denotes any number of any characters. If a line matches this overall pattern, sed produces no output; otherwise it echoes the line.
CHAPTER 24 TEXT-PROCESSING ONE-LINERS
The effect of this is to echo the original contents of the file, minus any commented lines (those beginning with #). The sed output is piped into an awk one-liner that filters out lines of length 0. The resulting sequence is a quick way to remove all blank and commented entries of a file.
sed -e "s/#.*//g" /etc/ntp.conf | awk '{if(length !=0) print $0}'
The output will, of course, be specific to the file used as input.
Conducting Dual Search and Replace with sed
A more advanced search and replace first checks the input for a string other than the one that is going to be replaced, and performs the search-and-replace operation only if this string is found. For instance, you might have a file in which each line contains a name and address, and you want to change Portland to Gresham on the lines containing the name Ron Peters. This can be accomplished using sed by including a pattern before the search expression. Continuing with our quick brown fox example, the following code first searches for the word quick in the input and then replaces all instances (g) of the string he with the replacement string she on the line if the word was found.
echo $VAR | sed -e "/quick/s/he/she/g"
Here s the output:
Tshe quick brown fox jumped over tshe lazy dog.
Filtering Lines with sed
Sometimes filtering out certain lines is desirable. For instance, when parsing ps output, you might not want the header line displayed. The following sed example removes the first line from the stdout of a call to ps. This is similar to the head command, but it has the opposite effect: while a head command grabs the specified number of leading lines and drops the rest, our example removes the specified number of initial lines from the output of ps (here, 1) and displays the rest. (You could use the tail command, but you would need to know the total number of lines.) Removing more than the first line is as simple as changing the specified line to a range of lines; to remove the first three lines, you would change 1d to 1,3d.
ps -ef | sed -e '1d'
