At the end, it returns to my shell.  Ask if there's anything you can't
figure out.



Perfect. -i gives interactive shell so get prompts. -e exits on error.

Cheers

Tim

[Dorset] Multiple commands in bash

2015-03-12 Thread TimA 

Hi

I'd like to run multiple commands in Bash:

patch -m patchfile  hg diff  cd dir  make -s

but for audit purposes I'd like each command in the list to be echoed as 
run, even better I'd like the Bash prompt to appear too in front of each 
line.


I know that as an alternative I can put the commands in a script with 
#!/bin/bash -v to get the first requirement.


Cheers

Tim

Not sure if this is what you want, but something like the following might
work. It doesn't do the bash prompt since there is not way of getting the
current prompt output reliably, but if you just want a fake one for display
purposes, you could hard code it into the script. Also, it doesn't check
the exit codes and abort early, as the  would do, but that's easy enough
to add in.

#!/bin/bash

COMMANDS=()
COMMANDS[0]=echo 1
COMMANDS[1]=echo 2
COMMANDS[2]=echo 3

for ((i = 0; i  ${#COMMANDS[@]}; i++)) ; do
echo ${COMMANDS[$i]}
${COMMANDS[$i]}
done
