tar

tar in AIX by default does not support compression. You will need to incorporate with gzip command to have it tar and compress at the same time.

$ tar cvf test.tar test                             # pure tar only $ tar cvf - test | gzip > test.tar.gz        # tar and compress together

gzip / gunzip

$ gunzip -c test.tar.gz | tar tvf -           # list compress files $ gunzip -c test.tar.gz | tar xvf -           # decompress files

compress / uncompress
