I’m having trouble ignoring the first 5 lines of my file while sorting the rest. My current command sorts the entire file by the second item, however I need to skip the first 5 “header” lines. I need read it and write it to the same file.
Current Command
sort -f -t $ -k2n,2 -o /folder/File.txt /folder/File.txt
Example
2016/07/07 15:41:02 @24921 @ @ @-1 b$1$4$... a$2$5$...

Answer
This sorts lines 6 and after of the file while leaving the first 5 lines unchanged:
{ head -n5 file.txt; tail -n+6 file.txt | sort -ft$ -k2n,2; } >file.tmp && mv file.tmp file.txt
tcsh
Unlike bash
, ksh
, and zsh
, tcsh
does not support command grouping with {...}
. Instead try a subshell:
( head -n5 file.txt; tail -n+6 file.txt | sort -ft$ -k2n,2 ) >file.tmp && mv file.tmp file.txt
