@REM THIS IS A POLYGLOT SCRIPT - supporting payloads in Tcl, bash, sh and/or powershelll (powershell.exe or pwsh.exe) |
|
|
|
|
|
|
|
@REM It should remain portable between unix-like OSes & windows if the proper structure is maintained. |

@REM On windows, change the value of nextshell to one of the listed 2 digit values if desired, and add code within payload sections for tcl,sh,bash,powershell as appropriate. |
|
|
|
|
|
|
|
@REM This wrapper can be edited manually (carefully!) - or sh,bash,tcl,powershell scripts can be wrapped using the Tcl-based punkshell system |
|
|
|
|
|
|
|
@REM e.g from within a running punkshell: deck scriptwrap.multishell <inputfilepath> -outputfolder <folderpath> |
|
|
|
|
|
|
|
@REM On unix-like systems, call with sh, bash or tclsh. (powershell untested on unix - and requires wscript if security elevation is used) |
|
|
|
|
|
|
|
@REM Due to lack of shebang (#! line) Unix-like systems will probably (hopefully) default to sh if the script is called without an interpreter - but it may depend on the shell in use when called. |
|
|
|
|
|
|
|
@REM If you find yourself really wanting/needing to add a shebang line - do so on the basis that the script will exist on unix-like systems only. |

@REM -- cmd/batch file section (ignored on unix but should be left in place) |
|
|
|
|
|
|
|
@REM -- This section intended mainly to launch the next shell (and to escalate privileges if necessary) |
|
|
|
|
|
|
|
@REM -- Avoid customising this if you are not familiar with batch scripting. cmd/batch script can be useful, but is probably the least expressive language and most error prone. |
|
|
|
|
|
|
|
@REM -- For example - as this file needs to use unix-style lf line-endings - the label scanner is susceptible to the 512Byte boundary issue: https://www.dostips.com/forum/viewtopic.php?t=8988#p58888 |
|
|
|
|
|
|
|
@REM -- This label issue can be triggered/abused in files with crlf line endings too - but it is less likely to happen accidentaly. |
|
|
|

@REM -- Due to this issue -seemingly trivial edits of the batch file section can break the script! (for Windows anyway) |
|
|
|
|
|
|
|
@REM -- Even something as simple as adding or removing an @REM |
|
|
|
|
|
|
|
@REM -- From within punkshell - use: |
|
|
|
|
|
|
|
@REM -- deck scriptwrap.checkfile <filepath> |
|
|
|
|
|
|
|
@REM -- to check your templates or final wrapped scripts for byte boundary issues |
|
|
|
|
|
|
|
@REM -- It will report any labels that are on boundaries |
|
|
|
|
|
|
|
@REM -- This is why the nextshell value above is a 2 digit key instead of a string - so that editing the value doesn't change the byte offsets. |
|
|
|
|
|
|
|
@REM -- Editing your sh,bash,tcl,pwsh payloads is much less likely to cause an issue. There is the possibility of the final batch :exit_multishell label spanning a boundary - so testing using deck scriptwrap.checkfile is still recommended. |
|
|
|
|
|
|
|
@REM -- Alternatively, as you should do anyway - test the final script on windows |
|
|
|
|
|
|
|
@REM -- Aside from adding comments/whitespace to tweak the location of labels - you can try duplicating the label (e.g just add the label on a line above) but this is not guaranteed to work in all situations. |
|
|
|
|
|
|
|
@REM -- '@REM' is a safer comment mechanism than a leading colon - which is used sparingly here. |
|
|
|
|
|
|
|
@REM -- A colon anywhere in the script that happens to land on a 512 Byte boundary (from file start or from a callsite) could be misinterpreted as a label |
|
|
|
|
|
|
|
@REM -- It is unknown what versions of cmd interpreters behave this way - and deck scriptwrap.checkfile doesn't check all such boundaries. |
|
|
|
|
|
|
|
@REm -- For this reason, batch labels should be chosen to be relatively unlikely to collide with other strings in the file, and simple names such as :exit or :end should probably be avoided |
