removing extra spaces
I have a variable col_head which contains the string " Date Time User Module Description Table Description Key Mode"
I want to remove extra spaces. I am using tr -s command. I am using in the way: tr -s col_head , but it is giving error. What is the correct way of using it? |

Wich extra spaces? If you mean the leading space:
Code:
col_head=$(echo "$col_head" | sed 's/^ //') |
