Dear Student,

5. Syntax is: sed -i <line number>r<file-1> <file2->

command is: sed -i 14r/etc/passwd input_file.txt.

"i" will insert contents of "/etc/passwd" file to input_file.txt(specifify your input file).

6. head -n 6 file_name.txt && sed -n '7,26p' file_name.txt|sort && sed -n '27,$p' file_name.txt

3 parts in above command:

head -n 6 file_name.txt : Simply prints first 6 lines of input file

sed -n '7,26p' file_name.txt|sort : reads 7 to 26 lines from input file and sort the lines in alphabetical order then prints.

sed -n '27,$p' file_name.txt: Prints lines from 27 onwards from input file.

7. awk '{print "#"$0}' inputfile_name.txt

8. awk '$0 ~ /STUDENT/{print}' /etc/passwd >>input

9. awk '{print $NF,$0}' anaconda-ks.cfg | awk '{$NF=""}1'

10. awk '{print NR-1 "," $0}' inputfile
