Compare 2 files using awk but exclude header record from each file
Hi Forum.
I have 2 files (a.txt, b.txt) that I need to match on the first column but need to exclude the header records during comparison from each of the 2 files. This is what I have so far.
I am using HP UX and think this may be done with awk but bot sure.
I have a file with a several header records and undeneath many detail records I need to put in the header record the number of detail records above this header record and number of detail records below this header record

Guys....
Got a scenario in which I need to skip parsing the header record while I do an awk.
Does awk has the flexibility to accomplish this?.
If so, how do we do this?.
Thanks !!!

Hello Everyone
In my shell script, I am retrieving the cluster ID and node number of an LPAR using the following command -
lsclcfg -l
This command's output looks as follows -

Hi everyone,
I've really searched for a solution to this and this is what I found so far:
I need to sort a command output (here represented as a "cat file" command) and from the second down to the second-last line based on the second row and then print ALL the output with the specified section... (7 Replies)
Hi All,
File contains header row.. we need to exclude the header row...no need to validate the first row in the file.
Data in the file should take valid data(two columns)..we need to exclude the more than two columns in the file except the first line.

Hi! all
can any one tell me how to compare current record of column with next and previous record in awk without using array
my case is like this

Hi All,
i have script like ...

"18" "52010" "1059"
i am using the below code it's not taking the header row.

Hi Forum.
I'm struggling to find a solution for the following issue.
I have multiple files a1.txt, a2.txt, a3.txt, etc. and I would like to insert a tab-delimited header record at the beginning of each of the files.
This is my code so far but it's not working as expected.

Hi,
I have two input files; file1 and file2. I compare them based on matched values in 1 column and print selected columns of the second file (file2). I got the result but the header was not printed. i want the header of file2 to be printed together with the result. Then i did below codes:-

x2sys_solve
X2SYS_SOLVE(1gmt) Generic Mapping Tools X2SYS_SOLVE(1gmt)NAME
x2sys_solve - Determine systematic corrections from crossovers
SYNOPSIS
x2sys_solve -Ccolumn -TTAG -Emode [ COE_list.d ] [ -V ] [ -W ] [ -Z ] [ -bi[s|S|d|D[ncol]|c[var1/...]] ]
DESCRIPTION
x2sys_solve will use the supplied crossover information to solve for systematic corrections that can then be applied per track to improve
data quality. Several systematic corrections can be solved for using a least-squares approach. Note: Only one data column can be processed
at the time.
-T Specify the x2sys TAG which tracks the attributes of this data type.
-C Specify which data column you want to process. Needed for proper formatting of the output correction table and must match the same
option used in x2sys_list when preparing the input data.
-E The correction type you wish to model. Choose among the following functions f(p), where p are the m parameters per track that we
will fit simultaneously using a least squares approach:
c will fit f(p) = a (a constant offset); records must contain cruise ID1, ID2, COE.
d will fit f(p) = a + b * d (linear drift; d is distance; records must contain cruise ID1, ID2, d1, d2, COE.
g will fit f(p) = a + b sin(y)^2 (1980-1930 gravity correction); records must contain cruise ID1, ID2, latitude y, COE.
h will fit f(p) = a + b cos(H) + c cos(2H) + d sin(H) + e sin(2H) (magnetic heading correction); records must contain cruise ID1,
ID2, heading H, COE.
s will fit f(p) = a * z (a unit scale correction); records must contain cruise ID1, ID2, z1, z2.
t will fit f(p) = a + b * (t - t0) (linear drift; t0 is the start time of the track); records must contain cruise ID1, ID2, t1-t0,
t2-t0, COE.
OPTIONS
No space between the option flag and the associated arguments.
COE_list.d
Name of file with the required crossover columns as produced by x2sys_list. NOTE: If -bi is used then the first two columns are
expected to hold the integer track IDs; otherwise we expect those columns to hold the text string names of the two tracks.
-V Selects verbose mode, which will send progress reports to stderr [Default runs "silently"].
-W Means that each input records has an extra column with the composite weight for each crossover record. These are used to obtain a
weighted least squares solution [no weights].
-Z For -Ed and -Et, determine the earliest time or shortest distance for each track, then use these values as the local origin for time
duration or distance calculations. The local origin is then included in the correction table [Default uses 0].
-bi Selects binary input. Append s for single precision [Default is d (double)]. Uppercase S or D will force byte-swapping. Option-
ally, append ncol, the number of columns in your binary input file if it exceeds the columns needed by the program. Or append c if
the input file is netCDF. Optionally, append var1/var2/... to specify the variables to be read.
EXAMPLES
To fit a simple bias offset to faa for all tracks under the MGD77 tag, try
x2sys_list COE_data.txt -V -TMGD77 -Cfaa -Fnc > faa_coe.txt
x2sys_solve faa_coe.txt -V -TMGD77 -Cfaa -Ec > coe_table.txt
To fit a faa linear drift with time instead, try
x2sys_list COE_data.txt -V -TMGD77 -Cfaa -FnTc > faa_coe.txt
x2sys_solve faa_coe.txt -V -TMGD77 -Cfaa -Et > coe_table.txt
To estimate heading corrections based on magnetic crossovers associated with the tag MGD77 from the file COE_data.txt, try
x2sys_list COE_data.txt -V -TMGD77 -Cmag -Fnhc > mag_coe.txt
x2sys_solve mag_coe.txt -V -TMGD77 -Cmag -Eh > coe_table.txt
To estimate unit scale corrections based on bathymetry crossovers, try
x2sys_list COE_data.txt -V -TMGD77 -Cdepth -Fnz > depth_coe.txt
x2sys_solve depth_coe.txt -V -TMGD77 -Cdepth -Es > coe_table.txt
