How to create an folder path alias on ubuntu EC2 instance?












2















ubuntu 18.04 on AWS



I followed an answer on stackoverflow to create a path alias:



nano ~/.bashrc



alias myfolder='/home/xxx/pms'


When I try to cd



cd myfolder


I get:




No such file or Directory




But if I use the path it works.



I am not sure what the issue here is.



TIA

  • If you use alias "myfolder"="cd /home/xxx/pms" and source ~/.bashrc you'll be able to access your folder typing only myfolder on the terminal...

What you're trying



You may be thinking of the term alias as defined and used in Mac OS.



For ubuntu the command alias does something totally different. The command you have used is for creating new commands so you don't have to remember a longer command, or a longer command you type so much it is quicker to type the alias. For example, if I don't want to keep typing this command to launch a program:



java -jar /usr/local/bin/bfg-1.13.0.jar



You could create an alias called bfg in my Unix profile (or ~/.bashrc as you have) like this:



alias bfg='java -jar /usr/local/bin/bfg-1.13.0.jar'



From now on I can use bfg every time I want to run the java program.



What you really need



In Ubuntu what you're looking for is a symbolic link. A symbolic link is created with the ln command on Ubuntu (and all other Unix varieties). See the following example.



In the below example you can see a folder that already exists called pms in my home folder.



Thus its absolute path is /home/ubuntu/pms.



ubuntu@server:~$ ls -l

total 4

drwxrwxr-x 2 ubuntu ubuntu 4096 Mar 25 11:05 pms


Now I change to a mother directory where I want the link, what you are thinking of as an alias, and create the symbolic link with ln -s



ubuntu@server:~$ cd /tmp/

ubuntu@server:/tmp$ ln -s /home/ubuntu/pms myfolder


Now I'm able to change directory to this alias as you understand it.



ubuntu@server:/tmp$ cd myfolder/

ubuntu@server:/tmp/myfolder$ pwd

/tmp/myfolder


To be clear, an alias is a completely different thing in Unix & Linux land. The symbolic link I have made can be seen by listing the /tmp directory where I created it.



ubuntu@server:/tmp/myfolder$ cd /tmp

ubuntu@server:/tmp$ ls -l

total 16

lrwxrwxrwx 1 ubuntu ubuntu   16 Mar 25 11:06 myfolder -> /home/ubuntu/pms


The contents of the /tmp/myfolder are one and the same as /home/ubuntu/pms.

  • Yes. Files and folders seen and created in the symlinked folder (from the example) /tmp/myfolder and in the original /home/ubuntu/pms are actually the same files on the disk.

Tradisjonelle folkedrakter frå Aust-Telemark, truleg frå 1880-åra. Drakter som dette er grunnlaget for moderne bunadar. Foto: Axel Lindahl Bunad frå Eggedal i Buskerud fotografert i 1906. Bunad (frå kledebunad , der norrønt «búnaðr» har same rot som (føre)bu) er ei samnemning brukt om klesdrakter i tradisjonell nordisk stil — ofte utvikla frå folkedrakter, men likevel i ein eigen tradisjon. Ein bunad er typisk ei forseggjort og kostbar drakt, med mykje broderi, og med handsmidde smykke i gull eller sølv, særleg dei særeigne søljene, som obligatorisk prynad i tillegg. Bunad og bunadbruk er eit debattemne med mange ulike oppfatningar, til dømes om kva som er ein bunad, og om ein kan endra på utforminga av draktene eller ikkje. Den norske bunadrørsla går tilbake til folkedansrørsla og føregangsfolk som Hulda Garborg og Klara Semb. I dag blir bunad brukt som nasjonaldrakt. Festbunad er likestilt med galla-antrekk, og ofte nytta ved særskilde høve, som konfirmasjonar eller d
