For loop to get rid of first 2 lines(conditionally)
hello all,
I get data from different vendors and need to clean it up. Usually it pretty straight forward when i have files that only have headers....but in my case i have files that have a starting line of file name(and some junk info) and 2nd line is headers and the 3rd line is were the actual data starts....
all is good. I do below to get rid of the first 2 lines(junk info and headers)..
the above works just fine except now i am getting some data from vendors that ONLY have headers(file 4.txt below), so if i use the above it will also get rid of my data line as well...so how can i modify my simple for loop that will only get rid of headers(first line) in file4.txt and in other files get rid of first 2 lines...do note most of the data line do start out with a date(not sure if that can help)
hope it make sense...below is a sample file listing
cat file1.txt
cat file2.txt
cat file3.txt
cat file4.txt

dh_clean
DH_CLEAN(1) Debhelper DH_CLEAN(1)NAME
dh_clean - clean up package build directories
SYNOPSIS
dh_clean [debhelperoptions] [-k] [-d] [-Xitem] [file...]
DESCRIPTION
dh_clean is a debhelper program that is responsible for cleaning up after a package is built. It removes the package build directories, and
removes some other files including debian/files, and any detritus left behind by other debhelper commands. It also removes common files
that should not appear in a Debian diff:
#*# *~ DEADJOE *.orig *.rej *.SUMS TAGS .deps/* *.P *-stamp
It does not run "make clean" to clean up after the build process. Use dh_auto_clean(1) to do things like that.
dh_clean (or "dh clean") should be the last debhelper command run in the clean target in debian/rules.
FILES
debian/clean
Can list other files to be removed.
OPTIONS -k, --keep
This is deprecated, use dh_prep(1) instead.
-d, --dirs-only
Only clean the package build directories, do not clean up any other files at all.
-Xitem --exclude=item
Exclude files that contain item anywhere in their filename from being deleted, even if they would normally be deleted. You may use this
option multiple times to build up a list of things to exclude.
file ...
Delete these files too.
SEE ALSO debhelper(7)
This program is a part of debhelper.
