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? – waltinator Apr 14 '19 at 19:35
  • 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! :) – Geroch Apr 14 '19 at 19:48
