(1) Assume you write your DTrace
script on Windows
and run it on Unix
. Because Windows
uses \r\n
as EOL while Unix
uses \n
, if you execute it directly, following complain will occur:
: No such file or directory
The solution is to apply dos2unix
to convert file format before playing it.
(2) The shebang line of script only accepts 1
argument, and -s
option must be the last. For example:
#!/usr/sbin/dtrace -sq
Will generate following error:
dtrace: failed to open q: No such file or directory
While “#!/usr/sbin/dtrace -qs
” will be OK. To make additional options take effect, please use #pragma
directive:
#pragma D option ...
Reference:
Does DTrace script only support “#pragma D option ..”, not “-x option”?.
