    <p>I have created a script that goes through specific subdirectories of files and tells me how many files are in each sub-directory that start with s. My problem occurs when it is searching and the sub-directory has failed to be created. For some reason, when the sub-directory that this script is searching for does not exist, it replaces the output with another previously created variable????</p> <p>I am writing this in bash for linux.</p> <p>I am looking at the following subdirectories...</p> <pre><code>participantdirectory/EmotMRI participantdirectory/EmotMRI/firstfour/ participantdirectory/T1 </code></pre> <p>So, this is the output I should get, when the subdirectory exists and everything is ok. It is the same for all files (if it is correct).</p> <pre><code>/home/orkney_01/jsiegel/ruth_data/participants/analysis2/1206681446/20090303/14693 16 in firstfour 776 in EmotMRI folder 2 files in T1 folder </code></pre> <p>For a directory which does not have a subdirectory created, I get this output...</p> <pre><code>bash: cd: /home/orkney_01/jsiegel/ruth_data/participants/analysis2/2102770508/20090210 /14616/EmotMRI/firstfour/: No such file or directory /home/orkney_01/jsiegel/ruth_data/participants/analysis2/2102770508/20090210/14616 776 in firstfour 114 in EmotMRI folder 2 files in T1 folder </code></pre> <p>I think that, because firstfour is a subdirectory of EmotMRI, when firstfour folder hasn't been created, it substitutes the scan numbers in EmotMRI for this answer? The number of scans in EmotMRI (in this instance is correct). Here is my script below. If this is happening, how do I stop it from doing this?</p> <pre><code>for d in $(cat /home/orkney_01/jsiegel/ruth_data/lists/full_participant_list_location_may20) do if [ -d "$d" ] then gr="failed" er="failed" fr="failed" cd $d/EmotMRI/firstfour/ gr=$(ls s*| wc -l) echo " " echo "$d" echo "$gr in firstfour" cd $d/EmotMRI/ er=$(ls s*| wc -l) echo "$er in EmotMRI folder" cd $d/T1/ fr=$(ls s*| wc -l) echo "$fr files in T1 folder" cd $d/EmotMRI else echo "$d is currently not available in directory" fi done cd /home/orkney_01/jsiegel/ruth_data/ echo "Check complete" </code></pre> <p>I know you will probably have many improvements on this script, I am very new to linux. Thanks for your help, </p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
