General :: Shell Programming Using While Loop
Jun 28, 2010I am trying to do some shell programs. I tried some sites regarding the while loop, they give the structure as:
Code:
while [ n1 -lt 500 ]
do
echo $((n1+100))
done
But the below code also worked for me:
Code:
while ((n1 > 500))
do
echo $((n1+100))
done
By using (( )) I could use while, for. But the documentations didnt follow this way. I mainly use this for datastructure programming.

View 5 Replies View RelatedGeneral :: Get A Shell Script To Loop Through A Number Of Directories And Subdirectories?
Jul 27, 2010I'm looking to get a shell script to loop through a number of directories and subdirectories,looking for files that contain a particular substring, and renaming the file by replacing the search string with a different substring. For example if you had a directory full of folders that contained digital photos (along with various other files which would need to remain unaffected), and the intent was to remove the "DSC_" prefix from several thousand files buried within. I've whipped up a rather long-winded solution that works well for this purpose but chokes on directory names with spaces. I am reasonably sure there's a 2 or 3-liner that would accomplish this exact same task.
function investigate
{
path=$1
for file in `ls $1`

General :: Shell Script - Use Variable In A For Loop With Directory Path?
Jan 19, 2011I modified files in several directories, and need to run a diff on the backup I created before modifying the file.
I'm trying to compose a simple shell script to speed up the task, but getting a syntax error.
Here is what I have:
for i in DIR1 DIR2 DIR3 DIR4 DIR5 do;
diff /maindir/subdir/subdir/$i/filename.txt.old /maindir/subdir/subdir/$i/filename.txt;
done
I know the paths are valid, and if I run just the diff command with the actual DIR1 instead of $i it works.

Feb 9, 2010I have a directory that contains some files (over a 1,000) that have a '' in the filename. There are also some good files that I need to keep. therefore I need a script to delete based on inode.
What I have thus far:
list="$(ls -il /opt/PC/log/*RPOUT*.xml)" #this gives me the list
# I need to get the inode of.
for i in $list
do
find . -inum $i -exec rm -i {} ;
echo "delete file" $i >> /home/me/tmp/del_inode.txt
done
echo 'completed'
I know this is not right ... what I know is is the 'find' is. I need to loop through the $list gleaning inodes to get all the files with '' delete. I'm not sure how. The $i gives me the whole line. I just want the first position. set $() does not seem to work ...

Software :: Combine And Partially Overwrite Text Files?
May 18, 2010I need to overwrite the first say 50 or so lines of an xml file on an everyday basis. The first 50 lines of the file are always the same and the 50 lines they get replaced with are always the same. Is there a way to create a file with the 50 new lines and somehow copy/merge/overwrite the larger file such that the 50 original lines would be replaced but the remainder of the file would be untouched?This seems simple, there has to be a way to do it. I'm just not smart enough to figure it out.

General :: Loop Append Text To Text Files?
Jan 15, 2010may be an advanced question but I need to know how to do this. Here at work I am in charge of recruiting and we have about 1,000 resumes in already. All of the resumes are in a .pdf format. I need to rename every .pdf in the following format:{firstnameLastname}.pdfThe only way I know how to do this is to convert all the .pdf files to text, extract the name out of the first few lines of text, import into excel, and then use VBA to rename the files in mass:Here is my logic so far:~Deskop/a = houses all the .pdfresumesOpen terminal: Code: cd ~/Desktop/afor f in *.pdf; do pdftotext -raw $f; done That will convert all of the preceding resumes into text filesNow I would like to append the name of the text file into the last line of the text file. So, for example, for Resume1.txt, I want to append "Resume1.txt" to the last line within Resume1.txt. So after I run the command I open Resume1.txt and on the last line within I want to see "Resume1.txt" on the last line, at the end of the resume.How can I do this? I would like to use a loop and have the terminal append the filename to the body of the text file until all of the have been appended.
