zazzybob,
perl -pi -e '$_ = "" if ( $. == 1 );' large_file
I am trying to convert the above perl command line you reference to a script.
I am not sure what the -pi does for the command line. But what I have below works but I am wondering if it is efficent or should be done in another manner.
$ cat junk
#!/usr/bin/perl
open (infile, "+< /adsm/ACTIVITIES/CHANGES/TGA2_OBSOLETE_CLNUP/x ");
open (outfile,">/adsm/ACTIVITIES/CHANGES/TGA2_OBSOLETE_CLNUP/z");
while ( $line = <infile>) {
if ($. == 1) {
}
else {
print (outfile "$line");
}
} #end while
system ("cp /adsm/ACTIVITIES/CHANGES/TGA2_OBSOLETE_CLNUP/z /adsm/ACTIVITIES/CHANGES/TGA2_OBSOLETE_CLNUP/x");
close(infile);
close(outfile);

uudecode
UUENCODE(1) BSD General Commands Manual UUENCODE(1)
NAME
uuencode, uudecode -- encode/decode a binary file
SYNOPSIS
uuencode [-m] [inputfile] outputname
uudecode [-m | -p] [encoded-file ...]
DESCRIPTION
uuencode and uudecode are used to transmit binary files over transmission mediums that do not support other than simple ASCII data.
The following options are available:
-m Use base64 encoding.
uuencode reads inputfile (or by default the standard input) and writes an encoded version to the standard output. The encoding uses only
printing ASCII characters and includes the mode of the file and the operand outputname for use by uudecode.
uudecode transforms uuencoded files (or by default, the standard input) into the original form. The resulting file is named outputname as
recorded in the encoded file, and will have the mode of the original file except that setuid and execute bits are not retained; if the -p
option is specified, the data will be written to the standard output instead. uudecode ignores any leading and trailing lines.
EXIT STATUS
The uudecode and uuencode utilities exits 0 on success, and >0 if an error occurs.
EXAMPLES
The following example packages up a source tree, compresses it, uuencodes it and mails it to a user on another system.
tar czf - src_tree | uuencode src_tree.tgz | mail user@example.com
On the other system, if the user saves the mail to the file temp, the following example creates the file src_tree.tgz and extracts it to make
a copy of the original tree.
uudecode temp
tar xzf src_tree.tgz
SEE ALSO
gzip(1), mail(1), tar(1), uuencode(5)
STANDARDS
The uudecode and uuencode utilities conform to IEEE Std 1003.2-1992 (``POSIX.2'').
HISTORY
The uudecode and uuencode utilities appeared in 4.0BSD.
BUGS
The encoded form of the file is expanded by 35% (3 bytes become 4 plus control information).
