uptime | cut -d " " -f 4,5,6,7 | cut -d "," -f 1,2
The output of this command is 1 day, 20:07.
And I want to add "Uptime: " before "1 day".
(I want cut to output Uptime: 1 day, 20:07)
Is it possible to do it using cut?
And yes, I can do it using awk (uptime | cut -d " " -f 4,5,6,7 | cut -d "," -f 1,2 | awk '{print "Uptime:",$1,$2,$3}'). But I need to know if we can do it using cut as well. :)
awk may be a better and easier solution for this.
uptime | awk '{sub(/,/,"",$5); print "Uptime: " $3,$4,$5}'
The answer would be no. According to the manual, the job of the command is to print selected text, not adding text:
CUT(1)
NAME cut - remove sections from each line of files
SYNOPSIS cut OPTION... [FILE]...
DESCRIPTION Print selected parts of lines from each FILE to standard output.
The closest is to add a custom output delimiter:
--output-delimiter=STRING use STRING as the output delimiter the default is to use the input delimiter
But that's not what you need in this case.
You can't insert anything with cut.
I would suggest using sed to insert the Uptime: string instead.
uptime | sed 's/.*up/Uptime:/' | cut -d, -f -2
