Any difference between EVAL and EXEC

I would like to know if there is any difference between EVAL and EXEC, to me they give the same results. Does anything differ in any other case(s)?

Code: Select all

<awyeah> .tcl eval pwd
<adapter> Tcl: /usr/home/elite/eggdrop
<awyeah> .tcl exec pwd
<adapter> Tcl: /usr/home/elite/eggdrop
<awyeah> hmm same results

well, for starters, 'eval pwd' executes the tcl command 'pwd', while 'exec pwd' executes the shell command 'pwd'.

try using:
exec die
and then:
eval die
and you know the diffrence

No I don't use eval or exec, on my scripts because they are not related to mostly tasks I script. Just wanted to get an idea from people.
