Shell scripts aren't particularly well suited to skipping over chunks of data that may contain data that is binary (rather than textual) contents of a file. Even if all of the files that are included in the tar file are text files, the shell and awk aren't necessarily a good fit for this job. Instead of showing us a broken awk script that doesn't do what you want to do; why don't you tell us what you are trying to do and show us output from the command:
Code:
tar -tvf filename.tar.gz
or if that doesn't work:
Code:
zcat filename.tar.gz | tar -tvf -
and show us exactly what output you want your shell/awk script to produce when given this gzipped tar archive (or the unzipped tar archive) as input?

Hi all!
A bit of background: I am trying to create a script that formats SQL statements. I have gotten so far as to add new lines based on certain match criteria like commas, keywords etc. In the process, I end up adding newlines where I don't want.
For example: substr(colName, 1, 10)... (3 Replies)

tar_append_file
tar_append_file(3) C Library Calls tar_append_file(3)NAME
tar_append_file, tar_append_eof, tar_append_regfile - append data to tar archives
SYNOPSIS
#include <libtar.h>
int tar_append_file(TAR *t, char *realname, char *savename);
int tar_append_regfile(TAR *t, char *realname);
int tar_append_eof(TAR *t);
VERSION
This man page documents version 1.2 of libtar.
DESCRIPTION
The tar_append_file() function creates a tar file header block describing the file named by the realname argument, but with the encoded
filename of savename. It then sets the current header associated with the TAR handle t to the newly created header block, and writes this
block to the tar archive associated with t. If the file named by realname is a regular file (and is not encoded as a hard link),
tar_append_file() will call tar_append_regfile() to append the contents of the file.
The tar_append_regfile() function appends the contents of a regular file to the tar archive associated with t. Since this function is
called by tar_append_file(), it should only be necessary for applications that construct and write the tar file header on their own.
The tar_append_eof() function writes an EOF marker (two blocks of all zeros) to the tar file associated with t.
RETURN VALUES
On successful completion, these functions will return 0. On failure, they will return -1 and set errno to an appropriate value.
ERRORS
The tar_append_*() functions will fail if:
EINVAL Less than T_BLOCKSIZE bytes were written to the tar archive.
EINVAL Less than T_BLOCKSIZE bytes were read from the realname file.
They may also fail if any of the following functions fail: lstat(), malloc(), open(), read(), th_write(), or the write function for the
file type associated with the TAR handle t.
