It’s evident that you’ve managed to mess up your PATH variable. (Your current PATH doesn’t contain any location where common utilities are located.) Try: PATH=/bin:/usr/bin:/usr/local/bin:${PATH} export PATH Alternatively, for “resetting” zsh, specify the complete path to the shell: exec /bin/zsh or exec /usr/bin/zsh
The command you are seeking is comm. eg:- comm -12 1.sorted.txt 2.sorted.txt Here: -1 : suppress column 1 (lines unique to 1.sorted.txt) -2 : suppress column 2 (lines unique to 2.sorted.txt)

Here’s yet another solution. This uses POSIX substring parameter expansion, so it works in Bash, Dash, KornShell (ksh), Z shell (zsh), etc. test “${string#*$word}” != “$string” && echo “$word found in $string” A functionalized version with some examples: # contains(string, substring) # # Returns 0 if the specified string contains the specified substring, # otherwise … Read more
You can try this: #!/bin/sh nohup java -jar /web/server.jar & The & symbol, switches the program to run in the background. The nohup utility makes the command passed as an argument run in the background even after you log out.
You have to pass the -np/–no-parent option to wget (in addition to -r/–recursive, of course), otherwise it will follow the link in the directory index on my site to the parent directory. So the command would look like this: wget –recursive –no-parent http://example.com/configs/.vim/ To avoid downloading the auto-generated index.html files, use the -R/–reject option: wget … Read more
I believe you should use : bc For example: echo “scale = 10; 123.456789/345.345345” | bc (It’s the unix way: each tool specializes to do well what they are supposed to do, and they all work together to do great things. don’t emulate a great tool with another, make them work together.) Output: .3574879198 Or … Read more
