Given the simple assumption that a marker should be a smaller value in the first column than in the line previus for creation of a new file the following should do in bash:
I am trying to cut the first 10 characters from a file only if the file has 'xyz' in field 185-188.
I tried this
cat filename | cut -c1-10
but this gives me all the records regardless of what is in field 185-188.
Is this doable ?
Thanks in advance for responses. (2 Replies)

gpiv_t-avg
GPIV_T-AVG(1) General Commands Manual GPIV_T-AVG(1)NAME
gpiv_t-avg - Calculates time-averaged mean and variances of PIV data.
SYNOPSIS
gpiv_t-avg [-dn | --dir_name dir basename] [-df | --first_dir N] [-dl | --last_dir N] [-fb | --file_basename file basename] [-ff |
--first_file N] [-fl | --last_file N] [-fx | --file_prefix] [-h | --help] [-n | --none] [-p | --print] [-relrms] [-uv | --print] [-v |
--version]
DESCRIPTION
gpiv_t-avg calculates mean and variances from a series of piv data resulting into time-averaged values. If no parameters are defined at the
command line, standard parameters will be used that are defined in the script. This program does not use the parameter resources from libg-
piv.
Options-dn | --dir_name dir base-name
The dir base-name represents the directory name without its last number. It is supposed that the last number in the directory name
is a counter.
-df | --first_dir
Defines the counter N of the first directory number at which the analyses starts.
-dl | --last_dir
Last directory number N at which the analyses ends.
-fb | --file_base_name file base-name
The filename has to be given without its .piv extension. The file base-name represents the file name without its last number, before
the extension. If not -fx key is used, it is supposed that the last number in the file name is a counter. The output will be written
to dir base-name/file base-name.ta_mean.piv and dirname/filename.ta_sdev.piv at which mean values and variances are written respec-
tively or to dirname/filename.ta_U.piv and to dirname/filename.ta_V.piv if -uv is used.
-ff | --first_file
Defines the counter Nof first file number at which the analyses starts.
-fl | --last_file
Last file number N at which the analyses ends.
-fx | --file_prefix
Prefix numbering to file base name.
-h | --help
On-line help.
-n | --none
Suppresses real execution.
-p | --print
Prints parameters, command line options and input and output filenames to stdout.
-relrms
Prints relative rms, related to the absolute mean value.
-uv Writes U and v displacements/velocities to separate outputs.
-v | --version
Prints version information to standard output, then exits successfully.
