Homework and Emergencies Homework & Coursework Questions How to display in column format? Post 302922892 by junior-helper on Wednesday 29th of October 2014 12:48:59 AM

If you can follow and understand following code, you should be able to easily adjust it for you needs with only few minor modifications. Hope it helps.


Simple for loop:
Code:
for shell in bash ksh tcsh
do
 echo "$shell"
done



Assigning value to variable in the for loop:
Code:
for shell in bash ksh tcsh
do
 path=$(which "$shell")
 echo "$shell: $path"
done



Column format, simplified, utilizing tabulator:
Code:
for shell in bash ksh tcsh
do
 path=$(which "$shell")
 echo -e "$shell\t$path" # you can exchange $shell and $path anytime
done



Column format, utilizing printf (for perfect alignment)
Code:
for shell in bash ksh tcsh
do
 path=$(which "$shell")
# First column format: 5 chars left-aligned
# Second column format: 15 chars right-aligned
 printf '%-5s %15s\n' "$shell" "$path"
done
