如何從其掛載的映像中重建 ISO 刪除文件?

  • July 9, 2018

我建構了一個 ISO,其中包含例如:

Directory listing of /
d---------   0    0    0            2048 Mar 19 2015 [     29 02]  .
d---------   0    0    0            2048 Mar 19 2015 [     29 02]  ..
d---------   0    0    0            4096 Mar 19 2015 [     32 02]  target-rpms
d---------   0    0    0            2048 Mar 19 2015 [     34 02]  vat
Directory listing of /target-rpms/
d---------   0    0    0            4096 Mar 19 2015 [     32 02]  .
d---------   0    0    0            2048 Mar 19 2015 [     29 02]  ..
----------   0    0    0        32435902 Mar 18 2015 [     85 00]  file1.rpm
----------   0    0    0         2055833 Mar 18 2015 [  15923 00]  file2.rpm
Directory listing of /vat/
d---------   0    0    0            2048 Mar 19 2015 [     44 02]  .
d---------   0    0    0            2048 Mar 19 2015 [     29 02]  ..
----------   0    0    0               0 Apr 20 2015 [  56633 00]  file1.txt

我想從 ISO 掛載的映像中添加/刪除文件,所以我做了:

 sudo mount -o loop,ro /full/path/to/file.iso /mounted/path

為了添加文件,我找到了這個方法:

mkdir /path/where/put/addedFile/vat/
cp prova.txt /path/where/put/addedFile/vat/prova.txt
mkisofs -o /tmp/test.iso -A test-1.0 -copyright 'Test' -joliet-long -RU
-uid 0 -gid 0 -iso-level 4 /mounted/path /path/where/put/addedFile

可行,mkisofs將文件合併到目錄中並test.iso包含所有所需的文件。

我需要一些關於如何在沒有的情況下創建的幫助test.iso,例如target-rpms/file2.rpm.

我知道我可以使用以下程序來做到這一點:

mkdir /path/where/rebuildIso
cp -R /mounted/path /path/where/rebuildIso
rm /path/where/rebuildIso/target-rpms/file2.rpm
mkisofs -o /tmp/test.iso -A test-1.0 -copyright 'Test' -joliet-long -RU
-uid 0 -gid 0 -iso-level 4 /path/where/rebuildIso

但是,由於 iso 維度,我想避免cp命令。

我在 Red Hat Enterprise Linux AS 第 3 版(Taroon Update 2)上使用 mkisofs 2.01 (i686-pc-linux-gnu)

事實上 mkisofs 2.01 指向 genisoimage:

$ mkisofs --version
mkisofs 2.01 is not what you see here. This line is only a fake for too clever
GUIs and other frontend applications. In fact, this program is:
genisoimage 1.1.11 (Linux)

man genisoimage可以嘗試以下-m選項:

-m glob
         Exclude files matching glob, a shell wildcard pattern, from being written to CD-ROM.  glob may match either the filename component or the full pathname.  This option may be used multiple times.  For example:

              genisoimage -o rom -m '*.o' -m core -m foobar

         would exclude all files ending in `.o', or called core or foobar from the image.  Note that if you had a directory called foobar, it too (and of course all its descendants) would be excluded.

  -exclude-list file
         A file containing a list of shell wildcards to be excluded.  See -m.
