sed-e ' S/jon/jonathan/datafile
2. Delete the first three rows
sed-e ' 1,3d ' datafile
3. Display 5-10 rows
sed-n ' 5,10p ' datafile
4. Delete the row that contains lane.
sed-e '/lane/d ' datafile
5. Show all birthdays between November-december lines

10. Write a script that will:
. Insert the title personnel FILE before the first line.
. Delete Wages ending in 500
. display file contents, reverse the surname and name
. Add the end at the end of the file

To create an SED script step:
1, create a script
Such as:

Code:

Avalee//home/javalee/x>cat Sedfile#this is Sedfile1ithis is example$ aend

2. Execute Sedfile script with Sed-f

Code:

Javalee//home/javalee/x>sed-f sedfile datafilethis is Examplesteve blenheim:238-923-7366:95 Latham Lane, Easton, PA 8 3755:11/12/56:20300....vinh tranh:438-910-7449:8235 Maple Street, Wilmington, VM 29085:9/23/63:68900end

The above database contains names, phone numbers and donations in the last three months
1. Show All phone numbers
Awk-f ":" ' {print $} ' datafile
2. Show Dan's phone number
Awk-f ":" '/^dan/{print $ ' datafile
3. Show Susan's name and phone number
Awk-f ":" '/^susan/{print $1,$2} ' datafile
4. Show all surnames starting with D
Awk-f ":" ' {print $} ' datafile | awk ' {print $} ' |awk '/^d/'
5. Show all names beginning with a C or E
Awk-f ":" ' {print $} ' datafile | awk ' {print '} ' |awk '/^[ce]/'
6. Show all names with only four characters
Awk-f ":" ' {print $} ' datafile | awk ' {if (length ($) ==4) print $} '
7. Show all names with area code 916
Awk-f ":" '/\[916\]/{print $ ' datafile
8. Show Mike's donation. Each value is displayed with a $ start. such as $250$100$175
Awk-f ":" '/^mike/{print "$" $ "$" $ "$" $4 "$" $ $ "datafile
9. Display last name followed by a comma and name, such as Jody,savage
Awk-f ":" ' {print $} ' datafile | awk ' {print $, ', ', ' $ '
10. Write an awk script that functions as:
Displays the full name and phone number of the savage.
. Show donations for Chet
The names of all the first one-month donations are displayed.
Note: The area code is originally indicated by parentheses.
The script is as follows:
#!/bing/awk-f
Begin{fs= ":"}
{if ($ ~/savage/) print $ ":" $ $}
{if ($1}~/^chet/) print "$" $ "$": $ "$4": $ "$"
{if ($3==250) print $}
11. Write an awk script that functions
. Total contributions to the output of the owner
. Average number of contributions to output 12 persons
. Output the maximum number of individual quarterly donations
. Output the minimum value of a single quarterly donation
The script is as follows:

begin{ Fs= ":"; Total = 0; Average = 0; } { if (nr==1) { Max = $ $; Min = $ $; } Total = $ $ + $4 + $; for (i=3; i<=nf; ++i) { if ($i > Max) { max = $i; } if ($i < min) { min = $i; } } } end{ Average = TOTAL/12; printf ("total =%d\n", total); printf ("average =%d\n", average); printf ("max =%d\n", max); printf ("min =%d\n", min); }
