Programming :: Bash - Read Content Of File To Variable And Use This Variable In For Loop ?

Aug 21, 2009

I'm trying to read content of file to variable and use this variable in for loop. The problem is, when I have c++ comment style in file - /*. Spaces in line are also interpreted as separated lines.

For example:

Code:

Changing $files to "$files" eliminate these problems but causes that whole content of variable is treated as one string (one execution of loop).

Programming :: Make A New Variable With The String From The Old Variable Btut Without Any Plus Sign?

Apr 7, 2010

my script has a variable which comes in the form +00.00 +0.00 -00.00 or -0.00 (the numbers can be any in that form) for any that have a + symbol I need to remove the +, but if it has a - symbol it needs to stay.

i need to make a new variable with the string from the old variable btut without any plus sign. I have tried a lot of different ways with no success, each thing I tried either left the + or removed the entire string. I think this should work but doesn't

foo=+12.40
bar=${foo#+}

Programming :: Choice Of Programming Solutions For Collated Document Repository?

Feb 18, 2011

We have documents on multiple workstations and want to collate them into a single repository to provide text search and download. So far we have implemented rsync to copy files from each workstation under a directory for each workstation on a server (incidentally providing a backup) and have set up text search using Xapian with Omega; users access it via a web browser. Still to do is to set up a system to copy files from each workstation's area on the server to the repository.

Many files are duplicated. In these cases we want to preserve the names but keep a single copy of the file;hard links can be used for that.For each file to be copied from a workstation's area into the collated area we need to check whether it is a duplicate (file size and, if same, MD5 sum) and if so, create a hard link to the original rather than create a copy.A system to detect and replace duplicates in the collated area has been written using ruby and postgresql but the developer cannot commit to continuing this work. It does mean we have a postgresql database populated with "fingerprints" of files in the collated area.My first priority is to get the system working; in the longer term whatever is developed must be maintainable; I do not yet know which language skills are available locally.

I am fluent in bash and competent with awk. Ruby looks nice but I have started to learn python and do think it prudent to learn both at the same time. Python's postgresql capabilities are not settled but may be fine for the simple usage required.What to do? A bash solution would run very slowly but could be developed quickly. Language knowledge aside, I have found it difficult to install ruby on the server (CentOS 5.5;installed rvm but "gem" still not installed; seems a very complex system with its own package management).

Programming :: Using Variable In A Command?

Apr 14, 2011

i'm trying to execute a shell script, i'm trying to use the values in an array for use in a sed command:

sed -n '/Sales ID: ${array[$i]}/,/Totals:/p'

that command creates empty files. so my guess is that its not recognizing the array as an array but as text?
how would i be able to utilize the array in the command? i got it, didnt think that if i doubled up the single quotes that it would work, but this worked:

sed -n '/Sales ID: '${array[$i]'}/,/Totals:/p'

Programming :: Variable Substitution In BASH?

Feb 17, 2011

Just a simple BASH for loop to read the file path from a text file (clean.txt) echo the variable for debug purposes, and scp it to a server I have using port 50 for SSH.

I've already formatted the entries in clean.txt to handle spaces correctly, using sed replacement.

Example from the clean.txt file:

Code:

/MP3/NAS000000001/Barenaked Ladies/Barenaked Ladies - Barenaked For The Holidays/14 Deck the Stills.mp3
