gunzip -c test.txt.gz | awk -F: '/^(Unzipped|Records|Record L)/{a[$1]+=$NF}END { for(i in a) print i FS a[i]}'
awk: a is not an array
record number 424033
After a lot testing....I got it work. One command line gunzip -c and get 3 output (Unzipped Bytes, Records, Record, Length) same time. Thanks
Code:
for Dtran in $(ls `cat $New_File`)
do
LETTER=`ls | awk -F. '{print $NF}' | sort -u`
case "$LETTER" in
"gz" )
echo "Filename : $Dtran" >> $README_FILE
echo " Data Format : ASCII with carriage returns and linefeeds" >> $README_FILE
echo " Compression : GZIP" >> $README_FILE
echo " GZIP Bytes : `ls -l $Dtran | awk '{print $5}'`" >> $README_FILE
gunzip -c $Dtran | awk 'BEGIN { l = 0 } { l = (length)+1 } { b += (length)+1 } END { print NR" "l-1" "b }' > /tmp/gunzip_${AUTO_JOB_NAME}
echo " Unzipped Bytes : `cat /tmp/gunzip_${AUTO_JOB_NAME} | awk '{print $3}'`" >> $README_FILE
echo " Records : `cat /tmp/gunzip_${AUTO_JOB_NAME} | awk '{print $1}'`" >> $README_FILE
echo " Record Length : `cat /tmp/gunzip_${AUTO_JOB_NAME} | awk '{print $2}'`" >> $README_FILE
printf '%s\n' >> $README_FILE

Hi All
This is very basic query but I have a huge folder named backup that I need to transfer.
What is the command to convert the file in format backup.tar.gz so that I could transfer the folder.
Is the command gzip filename?
Thanks

GZIP(1) BSD General Commands Manual GZIP(1)NAME
gzip -- compression/decompression tool using Lempel-Ziv coding (LZ77)
SYNOPSIS
gzip [-cdfhlNnqrtVv] [-S suffix] file [file [...]]
gunzip [-cfhNqrtVv] [-S suffix] file [file [...]]
zcat [-fhV] file [file [...]]
DESCRIPTION
The gzip program compresses and decompresses files using Lempel-Ziv coding (LZ77). If no files are specified, gzip will compress from stan-
dard input, or decompress to standard output. When in compression mode, each file will be replaced with another file with the suffix, set by
the -S suffix option, added, if possible. In decompression mode, each file will be checked for existence, as will the file with the suffix
added.
If invoked as gunzip then the -d option is enabled. If invoked as zcat or gzcat then both the -c and -d options are enabled.
This version of gzip is also capable of decompressing files compressed using compress(1) or bzip2(1).
OPTIONS
The following options are available:
-1, --fast
-2
-3
-4
-5
-6
-7
-8
-9, --best These options change the compression level used, with the -1 option being the fastest, with less compression, and the -9
option being the slowest, with optimal compression. The default compression level is 6.
-c, --stdout, --to-stdout
This option specifies that output will go to the standard output stream, leaving files intact.
-d, --decompress, --uncompress
This option selects decompression rather than compression.
-f, --force This option turns on force mode. This allows files with multiple links, overwriting of pre-existing files, reading from or
writing to a terminal, and when combined with the -c option, allowing non-compressed data to pass through unchanged.
-h, --help This option prints a usage summary and exits.
-l, --list This option displays information about the file's compressed and uncompressed size, ratio, uncompressed name. With the -v
option, it also displays the compression method, CRC, date and time embedded in the file.
-N, --name This option causes the stored filename in the input file to be used as the output file.
-n, --no-name This option stops the filename and timestamp from being stored in the output file.
-q, --quiet With this option, no warnings or errors are printed.
-r, --recursive This option is used to gzip the files in a directory tree individually, using the fts(3) library.
-S suffix, --suffix suffix
This option changes the default suffix from .gz to suffix.
-t, --test This option will test compressed files for integrity.
-V, --version This option prints the version of the gzip program.
-v, --verbose This option turns on verbose mode, which prints the compression ratio for each file compressed.
ENVIRONMENT
If the environment variable GZIP is set, it is parsed as a white-space separated list of options handled before any options on the command
line. Options on the command line will override anything in GZIP.

The gzip program was originally written by Jean-loup Gailly, licensed under the GNU Public Licence. Matthew R. Green wrote a simple front
end for NetBSD 1.3 distribution media, based on the freely re-distributable zlib library. It was enhanced to be mostly feature-compatible
with the original GNU gzip program for NetBSD 2.0.
This manual documents NetBSD gzip version 20040427.
