issues running bash file from any directory - bash

Not sure if this is operator error or if I just don't understand enough of what I am trying to do.
I have created cleardl.sh and put it in ~/bin and have also added ~/bin into $PATH, when I run echo $PATH it shows that it was added correctly.
If I am in ~/bin I can run ./cleardl.sh and it runs like it should, but if I try to run it from anywhere else I get a file not found error.
I have tried to make an alias for it but this also doesn't work more than likely due to me not knowing how to do that either.
Any help is appreciated.
Edit:
Moving the file to /usr/local/bin did get it working but then I deleted it to do some other tests and it kept working So it was likely me not having all the things correct at the same time.
Thanks for your help

Cd command is not working in shell script

I am trying to do cd command and i can see there is not change in path after that,not knowing what is the reason
I checked workarounds available in internet telling to give whole path,use alias etc but nothing worked out ,when i try manually doing cd its working and i tried giving this command in other dummy script there its working
But in my shell script even if i create one director and try to change also its not happening,code is actually getting stuck there and not going to other lines
Please suggest me what else i can so with this

Terminal says there is no file

enter image description here
PLEASE HELP! I can't seem to run my file. I've compiled it so it should run shouldn't it?
It also happens to my other files and I can't seem to fix it.
Ok, so a quick point of notice:
It is usually appreciated if you post your code directly in your question and use the code markup for that. It makes it easier to answer your question and prevents the image from turning into a dead-link at one point in time.
Then, regarding your code: it seems your Topic3ex1.c still has some errors, it always helps to fix them first. Maybe the errors are preventing Topic3ex1 (which I believe you have selected as the output file with the -o option? I am not familiar with gcc's syntax.) from being formed. Check if the file exist first by executing ls -a from the command line.
If you get a message saying "No such file or directory" while it is indeed there, this is usually caused by a lack of user rights. Try executing chmod u+x Topic3ex1.c and then run your command again. This will give your current user the right to execute the file (read up on chmod if you do not know it already, you will need it often).
Final question: is Topic3ex1 supposed to be a file or a folder? For if it is a file, then executing it like ./Topic3ex1 will only work if it is a shellscript (in that case, best rename your file to Topic3ex1.sh, its best to always mention the extension of the file). If it is a folder the ./ command won't do anything and the cd Topic3ex1 (cq. change directory-)command you where experiencing with will activate it as your working directory. If it is a file however, then the change directory command will, of course, be useless.

File disappeared after trying to move it in terminal

Can anyone tell me where my file may have gone after this command?
The file I'm missing is stats.cpp
And what is the correct command to move it from directory prog3a to prog3c?
Thank you.
Since you did not post the actual command you used I cannot tell you what happened to the file. What I can say is that unless you used the rm command, the file is not gone. Probably got its name changed if you cannot find it or it got moved somewhere else other than the intended destination.
The correct command you should use is
mv prog3a/stats.cpp prog3c/stats.cpp
This command should be run in the directory where both prog3a and prog3c folders exist (cd to it before running the command. This is assuming they're both inside the same directory).
A more specific answer can be provided if you tell us which command you initially ran specifically and the full paths of each folder.

install4j: Executing bash file

I am trying to run a bash file from install4j6. install4j does indeed try to run the bash file but it just returns an error at the end of the installation. The error is very generic and has no code reference or anything that will help me determine a solution - just a message that says "Error while executing file."
The only thing I can provide is how I have it setup in install4j6 since I am pretty sure that's my issue.
The bash file is defined in the root of my installation directory distribution tree and is named set_permissions.sh. For the sake of eliminating permissions being a cause, the file permission mode is set to 777 (both in install4j and on the file system).
I believe the issue is related to what I have set as my "working directory". I currently have it set to just ".". Is there a way to debug this further? Maybe get an actual error as to why it's not executing?
Ok, first a few things to check:
make sure that you're running the batch file after the install files step (you mention it being at the root of your install)
best to have the wait for termination checked and a variable for the return code.
redirect stderr to the log file (just in case)
As for working directory, . should work, but you can change it to ${installer:sys.installationDir} to make sure that it references the installation directory chosen by the user. You can also set the executable in the form of ${installer:sys.installationDir}\set_permissions.sh
Also, try and run just your shell script to make sure that it works :)

Cd in shell script not working

First off I am very very new to shell scripting. I am trying to write a script that takes in one parameter and then copies a folder in a different directory naming it using the parameter. This is the current code that I have:
#!/bin/sh
cd /var/www/html/fbplugin/chrome
sudo mkdir temp/$1
sudo cp -rf "/var/www/html/fbplugin/chrome/fbplugin" "/var/www/html/fbplugin/chrome/temp/$1"
When I run this code it says can't cd to /var/www/html/fbplugin/chrome. I'm not sure why it is saying this because I know the directory exists. I have copied the line directly and it works in terminal. If anyone could help me out that would be great.
If it matters in order to run the script I am typing "sh build.sh"
If that directory really exists, then you must have executed that script with a different user (cron, webserver, etc).
Check the rights for that directory.
I don't know why you're getting the error about cd, but it looks like you could just use absolute paths throughout. That would solve the larger problem of the script working correctly.
