Synopsis
Get parameter values
Syntax
pget [-abort] toolname parameter [ parameter2 ... ]
Description
`pget' gets the value of the specified parameter(s) from the given parameter file. All redirections and shell evaluations are performed.
Examples
Example 1
pget dmlist infile
Return the value of the infile parameter
Example 2
pget dmlist infile opt
Returns the value of the infile and opt parameters, one per line.
Example 3
pget dmlist infile.p_value
Will return the actual string stored in the parameter file for the value field of the parameter. Redirections and shell evaluations are NOT performed.
Example 4
pget -abort blah.par boo
The '-abort' option causes pget to exit with an error when a parameter file specifies an inappropriate value. For example, if blah.par contained
boo,i,h,notaninteger,,,"bad value"
the above command would exit with an error, rather than prompting for a valid value (as it would if '-abort' were not given). This can be useful in scripts, where prompting for a valid value could cause a script to hang indefinitely.
Parameters
| name | type | ftype | reqd |
|---|---|---|---|
| parameter_file | string | input | yes |
| parameter | string | input | yes |
| -abort | notype |
Detailed Parameter Descriptions
Parameter=parameter_file (string required filetype=input)
Parameter file from which to retrieve data
Name (plus optional path) of parameter file to get values from

Changes in CIAO 4.13
-
Internal cleanup to support newer compilers.
This applies to all parameter tools: paccess, pdump, pget, pline, plist, pquery, and punlearn.
-
Tool will now error out if it cannot write to any of the user-writable directories specified by the PFILES, PDIRS, or UPARM directories. The user-writable part is the colon separated list of directories listed first before the semi-colon.
