scripting

问题 I tried to make an "alias" for a path that I use often while shell scripting. I tried something, but it failed: myFold="~/Files/Scripts/Main" cd myFold bash: cd: myFold: No such file or directory How do I make it work ? However, cd ~/Files/Scripts/Main works. 回答1: Since it's an environment variable (alias has a different definition in bash ), you need to evaluate it with something like: cd "${myFold}" or: cp "${myFold}/someFile" /somewhere/else But I actually find it easier, if you just want

问题 I am fairly new to bash scripting and a part I am stuck on is after done< "$file_input" What I am trying to achieve is when I run the program ./test inside the testfile contains the numbers 15 14 90 22 and the program is going to take those numbers as the arguments and run it, but I am quite unsure how to do that. Am I going in the correct direction? Thanks for any help if [[ "$#" -ne 1 ]] then writeusage exit fi your_path=../file/test test_path=../../public/test file_input="$1" while read -r

问题 I am trying to learn bashing. I am trying to run ./test testcase the file in test case has the arguments 9 11 22 13, 32 35 32 16 on the next line and so on My program takes 4 arguments. Right now if testcase has one line of arguments i.e 3 5 6 7 it works fine, but when there is more than 2 it can't run the program properly. I know I need a while loop to read each line of the file, but I am stuck here. If someone could help me it would be greatly appreciated. Thank you in advance. I've asked

问题 If I have 3 different scripts to run at various times each time a file is written to, how would a bash script be written to run a specific script only at a specific time. This is not as simple as a cron job (though cron could probably swap out the .sh file based on time), I am looking for the time variables. For instance: If 9am-11:30 am run scriptA.sh if file.txt is changed. If 11:30am-5:45pm run scriptB.sh if file is changed. If 5:46pm-8:59am run scriptC.sh if file is changed. I asked a

问题 This question already has answers here : Why doesn't my Makefile interpolate an expression in a command (2 answers) Closed last year . Here's a simple command that works fine in my bash shell: echo "Created at: $(date)" >> README.md It appends Created at: Wed Jan 24 10:04:48 STD 2018 to README.md. However, ii I include the same command in my makefile, the behavior is different. makefile: README.md: echo "Created at: $(date)" >> README.md Running make README.md will treat the command

问题 I have data that is represented in this manner: { "key1": [{ "name": "some name1", "index": "some idx1" }, { "name": "some name2", "index": "some idx2" }, { "name": "some name3", "index": "some idx3" }], "key2": [{ "name": "some name4", "index": "some idx4" }, { "name": "some name5", "index": "some idx5" }, { "name": "some name6", "index": "some idx6" }] } I would like to convert the above to this, which is basically a dictionary with the existing key to a list of the indices. { "key1": [some

问题 All I want to do is differentiate between the program being run by the command line or by clicking the test.vbs file in a window. If you run the script by typing C:\testFolder\test.vbs in a command prompt, then I want the program to run differently than if you double clicked test.vbs in the testFolder . Is there some system variable that I can use to differentiate between the two scenarios? I first attempted to use WScript.Fullname to determine if the pathname ended in cscript or wscript. But

问题 I'm in a bash crash course today. This is a bash function that returns a value, via echo: #!/bin/bash get_hello_name() { echo 'Hello $1!' } msg=$(get_hello_name "x") echo $msg Output: $ bash ./initial_script5.sh Hello $1! I then incorrectly thought that the last echo was returned (I come from Java and Python), and was trying to use echo to debug the rest of the function. And then I was wondering why the heck I could not print out newlines in my echo statements, despite trying every single
