File Row Line Count without Header Footer
Hi There!
I am saving the file count of all files in a directory to an output file using:
wc -l * > FileCount.txt
I get:
114 G4SXORD
3 G4SXORH
0 G4SXORP
117 total
But this count includes header and footer. I want to subtract 2 from the count and get
112 G4SXORD
1 G4SXORH
0 G4SXORP
113 total
Is there a way to do that in a one-liner? How do I subtract 2 from wc -l output before writing it to output file?
Thanks

srf_info
srf_info(1) Staden io_lib srf_info(1)
NAME
srf_info - Lists information about the contents of an SRF file
SYNOPSIS
srf_info [-l bitmap] srf_archive ...
DESCRIPTION
srf_info lists some simple frequency metrics on the contents of an SRF file, both in terms of how many traces there are and the sort of
data held within them.
For efficiencies sake some control is given over which statistics to gather and display. This is controlled by the -l level parameter. The
value is the summation of one or more of the following values, representing the data to display.
1 Count of good/bad reads.
2 Counts and compressed size for selected chunk types.
4 Trace count and trace name prefix for each trace_header.
8 Base count.
OPTIONS
-l bitmap
Controls which statistics to gather and display. Bitmap is a value from 0 to 15 (1+2+4+8) as described in the DESCRIPTION section
above.
EXAMPLES
To count the total number of good and bad reads along with a break down of trace names per SRF data-block-header we would use bitmap values
1 and 4 combined.
srf_info -l 5 foo.srf
To count the total number of reads for all srf files in a directory.
srf_info -l 1 *.srf
