# sdr2file(1)

SDR data extraction test program

## NAME

sdr2file - SDR data extraction test program

## SYNOPSIS

**sdr2file** *configFlags*

## DESCRIPTION

**sdr2file** stress-tests SDR data extraction by retrieving and deleting all text file lines inserted into a test SDR data store named "testsdr*configFlags*" by the complementary test program [*file2sdr*(1)](/file2sdr/1.md).

The operation of **sdr2file** echoes the cyclical operation of **file2sdr**: each linked list created by **file2sdr** is used to create in the current working directory a copy of **file2sdr**'s original source text file. The name of each file written by **sdr2file** is file\_copy\_*cycleNbr*, where *cycleNbr* identifies the linked list from which the file's text lines were obtained.

**sdr2file** may catch up with the data ingestion activity of **file2sdr**, in which case it blocks (taking the **file2sdr** test semaphore) until the linked list it is currently draining is no longer empty.

## EXIT STATUS

- "0"

  **sdr2file** has terminated.

## FILES

No configuration files are needed.

## ENVIRONMENT

No environment variables apply.

## DIAGNOSTICS

- Can't use sdr.

  ION system error.  Check for diagnostics in the ION log file *ion.log*.

- Can't create semaphore.

  ION system error.  Check for diagnostics in the ION log file *ion.log*.
