PARGS(1)PARGS(1)NAMEpargs - print process arguments, environment variables, or auxil‐
SYNOPSISpargs [-aceFlx] [pid | core]...
The pargs utility examines a target process or process core file and
prints arguments, environment variables and values, or the process aux‐
pargs outputs unprintable characters as escaped octal in the format
\xxx, unless the character is one of the characters specified in the
"Escape Sequences" section of formats(5), in which case the character
is printed as specified in that section.
pargs attempts to be sensitive to the locale of the target process. If
the target process and the pargs process do not share a common charac‐
ter encoding, pargs attempts to employ the iconv(3C) facility to gener‐
ate a printable version of the extracted strings. In the event that
such a conversion is impossible, strings are displayed as 7-bit ASCII.
The following options are supported:
Prints process arguments as contained in argv (default).
Treats strings in the target process as though they were
encoded in 7-bit ASCII, regardless of the locale of the target.
The use of iconv(3C) is suppressed.
Prints process environment variables and values as pointed at by
the _environ symbol or by pr_envp in /proc/pid/psinfo.
Force. Grabs the target process even if another process has con‐
Displays the arguments as a single command line. The command line
is printed in a manner suitable for interpretation by /bin/sh. If
the arguments contain unprintable characters, or if the target
process is in a different locale, a warning message is displayed.
The resulting command line might not be interpreted correctly by
Prints process auxiliary vector.
The following operands are supported:
Process ID list.
Process core file.
Caution should be exercised when using the -F flag. Imposing two con‐
trolling processes on one victim process can lead to chaos. Safety is
assured only if the primary controlling process, typically a debugger,
has stopped the victim process and the primary controlling process is
doing nothing at the moment of application of the proc tool in ques‐
The following exit values are returned:
An error has occurred (such as no such process, permission
denied, or invalid option).
Process information and control files.
