cpio outpout

[Kevin Mc Gettigan]

I am verifying a tape using cpio and it is creating a 2.8Mb log file. Is there a switch on cpio I can use to display a summary of the dump, ie no. of file, no. of blocks, time taken, etc. to minimise the log file.
Cheers.

There's no summary available in cpio but you can use awk on the output, i.e.

time cat cpio.file | cpio -ictv | awk '{ numFiles++; numBlocks+=$3} END {printf("Files: %d\n Blocks: %d\n", numFiles, numBlocks}'

The time command will tell you how long it took, the awk script will tell you the number of files and the number of blocks.

Ignore the previous post, there is a missing bracket.
