I agree with RudiC that we need to see the first few lines of your input files. From the output you have shown us, it would seem that the most crucial would be:
Since you haven't bothered to tell us what operating system you're using, if od complains about unknown options, try od -bc instead of od -tx1c.
Before we see the output from the above commands, would anyone care to guess which of these files have DOS <CR><LF> line separators instead of UNIX line terminators? Unfortunately, even if this is the problem, I'm not seeing the output I would have expected.

Hello,
I have multiple functions within a shell script. eg. function_database_backup, unix_tar_creation, etc.
I would like to run these functions in parallel, as each is independent of the other.
If these were simple commands, I could have probably run each of the commands in background.

Hi.
I'm trying to speed up an rsync command by running it in parallel. There's no real option for this other than if the files are in multiple directories (which they're not). And even then there's no way of knowing if rsync has succeeded as the process is running in the background .. and... (4 Replies)

head
head(1) User Commands head(1)NAME
head - display first few lines of files
SYNOPSIS
/usr/bin/head
/usr/bin/head [-number | -n number] [filename]...
ksh93
head [-qv] [-n lines] [-c chars] [-s skip][filename]...
DESCRIPTION
/usr/bin/head
The head utility copies the first number of lines of each filename to the standard output. If no filename is given, head copies lines from
the standard input. The default value of number is 10 lines.
When more than one file is specified, the start of each file looks like:
==> filename <==
Thus, a common way to display a set of short files, identifying each one, is:
example% head -9999 filename1 filename2 ...
ksh93
The head built-in in ksh93 is associated with the /bin and /usr/bin paths. It is invoked when head is executed without a pathname prefix
and the pathname search finds a /bin/head or /usr/bin/head executable.
head copies one or more input files to standard output, stopping at a designated point for each file or to the end of the file whichever
comes first. Copying ends at the point indicated by the options. By default, a header of the form ==> filename <== is output before all but
the first file but this can be changed with the -q and -v options. If no file is given, or if the file is -, head copies from standard
input starting at the current location.
The option argument for -c and -s can optionally be followed by one of the following characters to specify a different unit other than a
single byte:
b 512 bytes
k 1-kilobyte
m 1-megabyte
For backwards compatibility, -number is equivalent to -n number.
OPTIONS
/usr/bin/head
The following options are supported by /usr/bin/head:
-n number The first number lines of each input file is copied to standard output. The number option-argument must be a positive decimal
integer.
-number The number argument is a positive decimal integer with the same effect as the -n number option.
If no options are specified, head acts as if -n 10 had been specified.
ksh93
The following options are supported by the head built-in command in ksh93:
-n Copy lines from each file. The default value is 10.
--lines=lines
-c Copy chars bytes from each file.
--bytes=chars
-q Never output filename headers.
--quiet|silent
-s Skip skip characters or lines from each file before copying.
--skip=skip
-v Always output filename headers.
--verbose
OPERANDS
The following operand is supported:
filename A path name of an input file. If no file operands are specified, the standard input is used.
USAGE
See largefile(5) for the description of the behavior of head when encountering files greater than or equal to 2 Gbyte ( 2^31 bytes).
EXAMPLES
Example 1 Writing the First Ten Lines of All Files
The following example writes the first ten lines of all files, except those with a leading period, in the directory:
example% head *
ENVIRONMENT VARIABLES
See environ(5) for descriptions of the following environment variables that affect the execution of head: LANG, LC_ALL, LC_CTYPE, LC_MES-
SAGES, and NLSPATH.
EXIT STATUS
The following exit values are returned:
0 Successful completion.
>0 An error occurred.
