====Using fda, pipe and search====

The <code>fda</code> (file do all) command in conjunction with <code>sys$pipe</code> and <code>search</code> can be quite helpful. Generally, use <code>fda</code> if you want to have a wildcard to capture many files in one command line, otherwise simply use <code>sys$pipe</code> and <code>search</code>.

It's easiest to simply see examples. In this case, read the ISQ headers and use <code>...</code> to include all subdirectories:

 $ fda ctheader dk0:[microct.data.0001234...]*.isq

Here we include all AIM files, no matter whether it's a C1234567.AIM or C1234567_SEG.AIM or whatever else:

 $ fda "aix -l" dk0:[microct.data.0001234.00005678]*.aim

Note the use of double-quotes around the target of the <code>fda</code> command when there are more than one strings in the command.

In this example we ensure the filename is exactly 8 characters using "%" instead of "*":

 $ fda aix dk0:[microct.data...]C%%%%%%%.AIM

[[Image:Bones2.jpg|20px]] <b>Warning! </b> It's a good practise to always test your wildcard usage with <code>dir</code> before applying a large command:

 $ dir dk0:[xxx...]*.aim

Combine <code>fda</code> with <code>sys$pipe</code> and <code>search</code>:

 $ pipe fda "aix -l" dk0:[microct...]*.aim | search sys$pipe "Slope"

And you can redirect the output into a file:

 $ fda/output=sys$scratch:all_headers.log aix dk0:[microct...]*.aim
 $ pipe fda type *.log | search sys$pipe "BV/TV" /output=BVTV.txt
 $ pipe fda/output=sys$scratch:zscan.txt "aix -l" C%%%%%%%.AIM | search sys$pipe "Original Creation-Date","Index Patient","Index Measurement","Patient Name","Site","Time"

Again, if the command consists of multiple words with spaces between (e.g. mcr ut:xxx.exe), then enclose the command in double-quotes.

 $ fda "mcr ut:uct_ext_header_display" dk0:[microct...]*.isq

Grab more than one line using <code>pipe</code> and <code>search</code> command:

 $ pipe aix *.aim | search sys$pipe "dim", "pos", "name"

Some common examples I use, without <code>fda</code>, are:

 pipe aix -l D0013580.AIM | search sys$pipe "Original file","Index Patient","Index Measurement","Patient Name","Site","Time"
 pipe ctheader D0013580.ISQ | search sys$pipe "Patient Name","Patient Index","Measurement Index","Creation Date","Site"
