Why doesn’t script work anymore?

      1. Update…

Uwe’s post about script reminded me that script just doesn’t seem to work for me for some reason anymore on Debian (both sarge and etch). I also see it sometimes on work’s RHEL-alike machines, but not all of them!

Here’s what happens:

$ script
Script started, file is typescript
bash: No such file or directory
Script done, file is typescript

What’s going on there? I’m sure it’s something simple. This has been happening for ages (more than a year) but I always get distracted when a simple search doesn’t turn up an answer to it. Any ideas?

Update… ^

huggie suggested I use strace to see what was going on. I have tried this before but I should have paid more attention, and done it again anyway, because now I can sort of see what is going on:

setsid() = 31937
ioctl(5, TIOCSCTTY) = 0
close(4) = 0
close(3) = 0
dup2(5, 0) = 0
dup2(5, 1) = 1
dup2(5, 2) = 2
close(5) = 0
execve("bash", ["bash", "-i"], [/* 22 vars */]) = -1 ENOENT (No such file or directory)

It is literally calling “bash” with no path. If I cd to /bin and do it then it works. Also this works:

$ SHELL="/bin/bash" script
Script started, file is typescript


$ echo $SHELL

I still don’t know what exactly is going on, but at least I have a workaround now.
