I'm running Ubuntu 18.04. My login shell is tcsh. Whenever I run
a script in this shell, there is about a half-second delay before
it executes. Suppose I make an empty file, tmp, in my home
directory, and make it executable (other scripts are similar).
If I enter "tmp" or "./tmp" or "/bin/tcsh tmp" or "/bin/tcsh
./tmp" or "/usr/bin/tcsh tmp", I get the delay. But if I enter
"/bin/bash tmp" or "source tmp" I don't. Making the file tmp
with only the line "#!/bin/tcsh" doesn't change anything.
But if tmp consists of the line "#!/bin/bash", then I don't
get the delay, even if I run "/bin/tcsh tmp". There must be a
simple solution, but I cannot, for the life of me, figure it out.

Any help appreciated.

  What's in /etc/csh.cshrc and ~/.tcshrc or ~/.cshrc?

  There is no file ~/.trcshrc, and ~/.cshrc contains about 10 aliases (Ls, Cp, etc), and some setting of the variable PATH. The file /etc/csh.cshrc is copied below: # /etc/csh.cshrc: system-wide .cshrc file for csh(1) and tcsh(1) if ($?tcsh && $?prompt) then bindkey "e[1~" beginning-of-line # Home bindkey "e[7~" beginning-of-line # Home rxvt bindkey "e[2~" overwrite-mode # Ins bindkey "e[3~" delete-char # Delete bindkey "e[4~" end-of-line # End bindkey "e[8~" end-of-line # End rxvt set autoexpand set autolist set prompt = " " endif

  Ahhhh . . . if I move .cshrc to x.cshrc (to tcsh doesn't find it), then all the delays disappear! So, it is something in that file. I can now go through, removing stuff, until I find out what it is. Thanks, waltinator. I knew it had to be simple! :)
