Thanks to "dgp" on freenode for this tip! % set decBackToHex [format %lx $hexInDec] ffffffffffff As per the "OPTIONAL SIZE MODIFIER" notation on http://tmml.sourceforge.net/doc/tcl/format.html.

I'm trying to do some fancy footwork with HEX numbers. Basically, I want to take a HEX number, convert to decimal, add some number (integer) to it, and convert it back to HEX. % set hex 0xFFFFFFFFFFFF 0xFFFFFFFFFFFF % set hexInDec [expr $hex] 281474976710655 % set decBackToHex [format %x...

Hi there! I'm trying to get Tcl to run a 'find this string in all of these files' type of command. From a shell (not Tcl), the following command works: find . -type f -exec grep -ni my_search_text /dev/null {} \; However, from Tcl, if we try to run: exec find . -type f -exec grep -ni $tag...

HA! You ALMOST had it BONG! Your idea of using "append" had no affect, however, the idea of placing EXEC within the string worked! set strCmd "exec tar -X /tmp/tar-exclude -cvvf /tmp/myarchive.tar /dir/to/tar" eval $strCmd This is great. Thanks so much both of your for your help...

PS: That error message is slightly massaged. The whole "ERROR: Could not compelete tar operation" and "Reason: " part are generated by my error catch proc. The "tar: /tmp/tar-exclude -cvvf /tmp/myarchive.tar /dir/to/tar: No such file or directory" is the raw output from tar failing.

Still nothing: I'll give specific details here: exec tar -X /tmp/tar-exclude -cvvf /tmp/myarchive.tar /dir/to/tar Works. set tarArgs "-X /tmp/tar-exclude -cvvf $tmp/myarchive.tar $/dir/to/tar" exec tar $tarArgs ERROR: Could not complete tar operation Reason: tar: /tmp/tar-exclude -cvvf...

Yes I'm positive it exists. I think the problem is that the 'exec' command typically works as: exec myexecutable arg0 arg1 arg2 However, when the args are stored as a variable: set args "args0 args1 args2" exec myexecutable $args it tries to pass "myexecutable" the args as an ENTIRE string...

Trying: exec "tar $tarArgs" Results in: ERROR: Could not complete tar operation Reason: couldn't execute "tar -Xcvf /tmp/tar-exclude-file /tmp/MYFILE.tar /dir/to/tar": no such file or directory

Having trouble getting exec to work with a dynamic set of arguments for the binary it's execing. Example: exec tar -cvf /tmp/MYFILE.tar /dir/to/tar This works, and the tar file is created. However, what if the 'arguments' passed into tar might change based on version? # If tar is newer...

I'm having the same type of question. I have some specific errors .. please see below ---- OS: Windows Vista Premium Tcl Version: 8.4 Goal: Looking for write capabilities with Serial Port. Code: # In Windows, we open a channel with "com1" =>set com [open com1: w] file14c4158 # Configure...
