It took me ages to learn bash redirection properly, and I still have to concentrate sometimes to keep my &s and my >s straight. Here's the lowdown in case you, too, have intermittent brain failure on this one.

In addition to the fairly common forms of input/output redirection the shell recognizes something called process substitution. Although not documented as a form of input/output redirection, its syntax and its effects are similar.

The Linux utility awk can create output redirection for data you want to save and it can use input redirection from commands or respond interactively with users.

If you're using Sudo, you've probably already discovered that the increased privileges apply only to the first command typed and don't extend to any input or output redirection.

The output of most GNU command line tools is normally sent to the terminal (ie – standard output). There are times when you would like to have the output saved as a file. Now, you could copy the text from the terminal and paste it into a text editor and save it, but there’s a better way...

If you want to Determine the throughput of a pipe you need to use cpipe. Cpipe copies its standard input to its standard output while measuring the time it takes to read an input buffer and write an output buffer. Statistics of average throughput and the total amount of bytes copied are printed to the standard error output.

This article is a continuation to my other Bash-related post, 6 Bash Productivity Tips. Since that article gathered many useful comments and I bumped into several more over the net, here are 5 more tips and tricks. Although these may not be necessarily productivity-related, they will surely ease working in a Bash terminal and it may be worth knowing them.
