How might I read a particular line from a text file using BASH?
I would like to specify the line number

thnx

Code:

line=$(sed -n '123p' file)

where 123 is the number.

How might I pass sed a variable without manually concatenating a string?

"123" needs to be a shell variable

line=$(sed -n '123p' file)

thnx

Just replace the single quotes with double quotes:

Code:

export var=123
line=$(sed -n "${var}p" file)

Cheers,
