Let’s do it more simply. If you are using tmux below version 1.7, append next line to ~/.tmux.conf: bind-key C-s run “for i in $(tmux lsw|awk -F: ‘{print $1}’); do tmux movew -s \$i; done” You could sort all windows, by typing PREFIX-KEY, then Ctrl + s. Else, if you are using tmux version 1.7 … Read more
You can also override the diff formatting behavior to get your desired behavior without using side-by-side mode: diff –new-line-format=”+%L” –old-line-format=”-%L” –unchanged-line-format=” %L” file1 file2 This command will show you the full file as context and be closest in format to diff -u file1 file2
Citing this source, Standard UNIX variables are split into two categories, environment variables and shell variables. In broad terms, shell variables apply only to the current instance of the shell and are used to set short-term working conditions; environment variables have a farther reaching significance, and those set at login are valid for the duration … Read more
No. What you can do is write a loop with kill -0 $PID. If this call fails ($? -ne 0), the process has terminated (after your normal kill): while kill -0 $PID; do sleep 1 done (kudos to qbolec for the code) Related: What does `kill -0 $pid` in a shell script do?
Try grep -f the_ids.txt huge.csv Additionally, since your patterns seem to be fixed strings, supplying the -F option might speed up grep. -F, –fixed-strings Interpret PATTERN as a list of fixed strings, separated by newlines, any of which is to be matched. (-F is specified by POSIX.)
The .bss section is guaranteed to be all zeros when the program is loaded into memory. So any global data that is uninitialized, or initialized to zero is placed in the .bss section. For example: static int g_myGlobal = 0; // <— in .bss section The nice part about this is, the .bss section data … Read more
Are you absolutely sure those individual files are not symbolic links? Rsync has a few useful flags such as -l which will “copy symlinks as symlinks”. Adding -l to your command: rsync -rtvpl /source/backup /destination I believe symlinks are skipped by default because they can be a security risk. Check the man page or –help … Read more
/path/to/file/**/*.js matches any number of directories between /path/to/file/ and /*.js. As opposed to /path/to/file/*/*.js, which matches a single directory between /path/to/file/ and /*.js.
Below code can be used to display the uncommon fields in two files, side by side. sdiff -l file1 file2 | cat -n | grep -v -e ‘($’ Below code will display common fields along with line numbers in the output. diff -y file1 file2 | cat -n | grep -v -e ‘($’
It sounds like you need sed: sed -n ‘/pattern/,/^$/p’ file Don’t print by default (-n). For lines that match /pattern/ up to an empty line /^$/, print.
