[Work] sed, awk, perl
sed, awk, perl

# Print the length of the longest input line:
awk '{ if (length($0) > max) max = length($0) }
END { print max }' data
# Print every line that is longer than 80 characters:
awk 'length($0) > 80' data
The sole rule has a relational expression as its pattern and it has no action—so the default action, printing the record, is used.
# Print the length of the longest line in data:
expand data | awk '{ if (x < length()) x = length() }
END { print "maximum line length is " x }'
The input is processed by the expand utility to change tabs into spaces, so the widths compared are actually the right-margin columns.
# Print every line that has at least one field:
awk 'NF > 0' data
This is an easy way to delete blank lines from a file (or rather, to create a new file similar to the old file but from which the blank lines have been removed).
# Print seven random numbers from 0 to 100, inclusive:
awk 'BEGIN { for (i = 1; i <= 7; i++)
print int(101 * rand()) }'
# Print the total number of bytes used by files:
ls -l files | awk '{ x += $5 }
END { print "total bytes: " x }'
# Print the total number of kilobytes used by files:
ls -l files | awk '{ x += $5 }
END { print "total K-bytes: " (x + 1023)/1024 }'
# Print a sorted list of the login names of all users:
awk -F: '{ print $1 }' /etc/passwd | sort
# Count the lines in a file:
awk 'END { print NR }' data
# Print the even-numbered lines in the data file:
awk 'NR % 2 == 0' data
