问题 How can we find specific type of files i.e. doc pdf files present in nested directories. command I tried: $ ls -R | grep .doc but if there is a file name like alok.doc.txt the command will display that too which is obviously not what I want.

问题 This is a duplicate of https://serverfault.com/questions/102098/powershell-script-showing-commands-run. I thought it would be more appropriate to ask this question here. I am playing around with PowerShell scripts and they're working great. However, I am wondering if there is any way to also show all the commands that were run, just as if you were manually typing them in yourself. This would be similar to "echo on" in batch files. I looked at the PowerShell command-line arguments, the cmdlets

问题 There are already two posts on stack overflow on this topic; however, none of them have resolved or addressed my specific situation. I have installed pytest via pip install pytest . I am able to import the library in Python as well. The problem is that when I try to use the py.test command in Terminal, I get py.test: command not found .

问题 Inside my "expect" script: set $REPOS "/path/to/repo/" set $REV 73 set LOG [spawn svnlook log -r $REV $REPOS] What this will store in the variable "LOG": 16345 (memory location). What it should store in the variable "LOG": "some message of the svn commit log". It seems like the is a problem with executing a bash command and then storing that output into an expect variable. Have you got any ideas? I am new to expect and tcl. 回答1: You did't need spawn there. Try: set LOG [exec svnlook log -r

问题 I'm trying to run a program and feed the program a script as such: subprocess.Popen(['X:\\apps\\Nuke6.1v5\\Nuke6.1.exe', '-t', 'X:\\apps\\Scripts\NUKE\\nukeExternalControl\\server.py']) My problem is that it takes the program a few seconds to finish launching. So while its starting up the program Popen runs the next command and of course because the program is not up and running is errors out. So my question is how do I tell Popen to wait for the first application to run THEN execute the next
