gzcat

Description

plakar gzcat reads gzip-compressed files from within snapshots and writes to the standard output, similarly to the standard Unix command gzcat(1), without holding the files in memory or requiring a complete file restore first: it is fast and suitable for large files.

Usage

plakar gzcat snapshotID:/path/to/file.gz [snapshotID:/path/to/file.gz]

Examples

Using grep to search for lines containing mda in the /var/log/maillog.0.gz file of snapshot c5, then using wc to count how many lines are in that file:

$ plakar gzcat c5:/var/log/maillog.0.gz | grep mda
[...]

$ plakar gzcat c5:/var/log/maillog.0.gz | wc -l
