OK, I have the following script (reduced, just enough to demonstrate the problem):
--- test.sh --- #!/bin/bash cmd="apt-cache search debian-installer | sort | egrep --color=always -i debian-installer" #tput nrrmc # line 3 #less -REf <($cmd) # line 4 less -REf <(bash -c "$cmd") # line 5 #less -REf <(tput nrrmc; bash -c "$cmd") # line 6 #less -REf <(bash -c "tput nrrmc; $cmd") # line 7 --- I am running this script in a plan xterm (no embedded screen session), bash shell. When I manually run lines 2 then 5 in xterm, I get expected output in my terminal. When I run test.sh from xterm, I get a blank screen, followed by return to the xterm, as though the script didn't do anything! I would like to understand why. Uncommenting line 3, does not fix the problem - same blanking output. Commenting out line 5, and uncommenting one of line 4, 6 or 7, also does not fix the problem. In fact, uncommenting line 4 gives an error, since the command is being substituted as though it is a single command, instead of a pipeline. I am wondering how I might fix this particular problem without using a full bash instantiation as seen in line 5 - line 7. With one of line 5 - line 7 uncommented, if I run from xterm: test.sh|less this also gives the expected output, but requires manual entry of "|less" command, which is part of what I want to avoid of course. (BTW, running test.sh inside a gnu screen session works 'as expected'.) TIA Zenaan -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe". Trouble?
