command-prompt

问题 This is a bit of a convoluted question, but here goes nothing! I've recently updated my bash prompt to the nice version appearing in the last post of this thread: Bash: custom PS1 with nice working directory path. The relevant bash code (from that thread post) is copied here: # define the awk script using heredoc notation for easy modification MYPSDIR_AWK=$(cat << 'EOF' BEGIN { FS = OFS = "/" } { if (length($0) > 16 && NF > 4) print $1,$2,".." NF-4 "..",$(NF-1),$NF else print $0 } EOF ) # my

问题 In gradle I'd like to add both the current branch-name and commit-number as suffix to my versionName. (Why? Because when I build my app in Jenkins to release it in HockeyApp, it's useful to show what branch & commit that app was built from!) So when I enter this in command prompt, my current branch name is returned: git rev-parse --abbrev-ref HEAD Same happens when I use this line in Android gradle, using the code in either this answer, or as shown in this piece of gradle code: def

问题 I have a large folder of .cbr's, and I'm renaming them by issue number to correctly order them.

For example, where n = initial number and m = final number: n.cbr, (n+1).cbr, ..., (m-1).cbr, m.cbr The .bat thusfar: ren *.cbz *.cbr ren *.cbr <increment numbers n through m>.cbr Alternatively, how do I trim each

问题 I'm trying to install pygame to work with python through pip, however when I use the command pip install pygame, it begins working and seems alright until it throws an error.

The application works perfectly fine when run from inside VS2010, but gives "ssh.dll missing from your computer. Reinstall the program" error when the same EXE is run from the command prompt. Any inputs as to why am I seeing this dual behaviour of the console application from inside and outside of VS2010? Thanks. 回答1: you should download ssh.dll by searching it in google .when the file

问题 I installed PostgreSQL on my laptop today (running Windows 10) and I am trying to get started learning SQL. The PostgreSQL Installation Tutorial said to try connecting using command prompt, by opening psql.exe, so I did that, got the command window, and it asked me for my password. I entered that and pressed the Enter key -- and the window disappeared. Multiple times. The password is definitely correct. What did I do wrong? I've looked hard for info about this but have not found answers. I'm
