How can i sort a .txt file without loosing the header information?
Hi,

I'm trying to sort 2 different .txt tab delimited files with the command line:

Code:
sort -k 1b,1 inputfile > outputfile

But doing that i'm also sorting the header (that ends at the end of my file).
How can i sort a .txt file without sorting the header but conserving the header in the output file?

My file looks like:

Code:
transcript_id	gene_id	length	effective_length	expected_count	TPM	FPKM	IsoPct
comp1000201_c0_seq1	comp1000201_c0	337	183.51	0.00	0.00	0.00	0.00
comp1000297_c0_seq1	comp1000297_c0	612	458.50	0.00	0.00	0.00	0.00
comp100036_c0_seq1	comp100036_c0	333	179.51	1.00	6.72	6.17	100.00
comp10003_c1_seq1	comp10003_c1	328	174.51	0.00	0.00	0.00	0.00
comp100041_c0_seq1	comp100041_c0	338	184.51	0.00	0.00	0.00	0.00

Thanks!

I also tried to use:

Code:
awk 'NR==1; NR > 1 {print $0 | "sort -t\| -n -k 1,1"}' file

and this is what i'm receiving:

Code:
awk: warning: escape sequence `\|' treated as plain `|'
transcript_id	gene_id	length	effective_length	expected_count	TPM	FPKM	IsoPct
sort: option requires an argument -- t
Try `sort --help' for more information.
sh: -n: command not found

LEARN ABOUT LINUX

irsend

IRSEND(1)							   User Commands							 IRSEND(1)

NAME

       irsend - basic LIRC program to send infra-red commands

SYNOPSIS

       irsend [options] DIRECTIVE REMOTE CODE [CODE...]

DESCRIPTION

       Asks the lircd daemon to send one or more CIR (Consumer Infra-Red) commands. This is intended for remote control of electronic devices such
       as TV boxes, HiFi sets, etc.

       DIRECTIVE can be:
	  SEND_ONCE	    - send CODE [CODE ...] once
	  SEND_START	    - start repeating CODE
	  SEND_STOP	    - stop repeating CODE
	  LIST		    - list configured remote items
	  SET_TRANSMITTERS  - set transmitters NUM [NUM ...]
	  SIMULATE	    - simulate IR event

       REMOTE is the name of a remote, as described in the lircd configuration file.

       CODE is the name of a remote control key of REMOTE, as it appears in the lircd configuration file.

       NUM is the transmitter number of the hardware device.

       For the LIST DIRECTIVE, REMOTE and/or CODE can be empty:

	  LIST	 ""    ""   - list all configured remote names
	  LIST REMOTE  ""   - list all codes of REMOTE
	  LIST REMOTE CODE  - list only CODE of REMOTE

       The SIMULATE command only works if it has been explicitly enabled in lircd.

       -h --help
	      display usage summary

       -v --version
	      display version

       -d --device
	      use given lircd socket [/var/run/lirc/lircd]

       -a --address=host[:port]
	      connect to lircd at this address

       -# --count=n
	      send command n times

EXAMPLES

	  irsend LIST DenonTuner ""
	  irsend SEND_ONCE  DenonTuner PROG-SCAN
	  irsend SEND_ONCE  OnkyoAmpli VOL-UP VOL-UP VOL-UP VOL-UP
	  irsend SEND_START OnkyoAmpli VOL-DOWN ; sleep 3
	  irsend SEND_STOP  OnkyoAmpli VOL-DOWN
	  irsend SET_TRANSMITTERS 1
	  irsend SET_TRANSMITTERS 1 3 4
	  irsend SIMULATE "0000000000000476 00 OK TECHNISAT_ST3004S"

FILES

       /etc/lirc/lircd.conf
	      Default lircd configuration file.  It should contain all the remotes, their infra-red codes and the corresponding timing	and  wave-
	      form details.

DIAGNOSTICS

       If lircd is not running (or /var/run/lirc/lircd lacks write permissions) irsend aborts with the following diagnostics:
       "irsend: could not connect to socket"
       "irsend: Connection refused" (or "Permission denied").

SEE ALSO

       The documentation for lirc is maintained as html pages. They are located under html/ in the documentation directory.
