| - | ==== Problem | + | * [[Relative file names in a tar archive]] |
| - | If we tar the following directory | + | |
| - | < | + | |
| - | % tree --charset=unicode /tmp/expt | + | |
| - | /tmp/expt | + | |
| - | `-- insurance | + | |
| - | |-- auto.txt | + | |
| - | |-- condo.txt | + | |
| - | `-- rv.txt | + | |
| - | 1 directory, 3 files | ||
| - | </ | ||
| - | using | ||
| - | < | ||
| - | % tar czvf insurance.tgz / | ||
| - | tar: Removing leading `/' from member names | ||
| - | / | ||
| - | / | ||
| - | / | ||
| - | / | ||
| - | </ | ||
| - | then the file names in the .tgz contain the whole path releative to '/' | ||
| - | < | ||
| - | % tar tzvf insurance.tgz | ||
| - | drwxr-xr-x rajulocal/ | ||
| - | -rw-r--r-- rajulocal/ | ||
| - | -rw-r--r-- rajulocal/ | ||
| - | -rw-r--r-- rajulocal/ | ||
| - | </ | ||
| - | But I want the paths to be relative to the ' | ||
| - | < | ||
| - | drwxr-xr-x rajulocal/ | ||
| - | -rw-r--r-- rajulocal/ | ||
| - | -rw-r--r-- rajulocal/ | ||
| - | -rw-r--r-- rajulocal/ | ||
| - | </ | ||
| - | ==== Solution ==== | ||
| - | Use the -C option while creating the tar archive. | ||
| - | < | ||
| - | % tar czvf insurance2.tgz -C /tmp/expt insurance | ||
| - | insurance/ | ||
| - | insurance/ | ||
| - | insurance/ | ||
| - | insurance/ | ||
| - | </ | ||
| - | Test the archive. | ||
| - | < | ||
| - | % tar tzvf insurance2.tgz | ||
| - | drwxr-xr-x rajulocal/ | ||
| - | -rw-r--r-- rajulocal/ | ||
| - | -rw-r--r-- rajulocal/ | ||
| - | -rw-r--r-- rajulocal/ | ||
| - | </ | ||
| - | ==== How it works ==== | ||
| - | From the man page | ||
| - | < | ||
| - | % man tar | ||
| - | ... | ||
| - | -C, --directory=DIR | ||
| - | Change | ||
| - | options that follow. | ||
| - | </ | ||
| - | |||
| - | ==== System information ==== | ||
| - | Debian Buster | ||
| - | < | ||
| - | % tar --version | ||
| - | tar (GNU tar) 1.30 | ||
