I am new to shell scripting and need some help. I googled, but couldn't find a similar scenario.
Basically, I need to rename a datafile. This is the scenario -
I have a file, readonly.txt that has 2 columns - file# and name.
I have another file,missing_files.txt that has id and name. Both the files are tab delimited.
This is how the 2 files look -
readonly.txt -
missing_files.txt-
Now, this is what I want -
loop through missing_files.txt and if the first column matches the first column in readonly.txt (by ignoring the leading 0s in the second file), then, give me the second column of that line.
For eg, the last line in readonly.txt is 52|/u01/oradata/yrr11.dbf. Now the first column matches the first column of the last line in missing_files.txt (It should not match the first line in missing_files.txt-since 00552 also has 52 in it), then I need to output missing00052.dbf.
This is the script that I have now -
The
doesn't do what I want.
Hi All,
I have written the below script that searches for the pattern in a file and delete them if present. please can some one have a look and suggest the changes in the script.

Dear awk users,
I am trying to use awk to match records across two moderately large CSV files. File1 is a pattern file with 173,200 lines, many of which are repeated. The order in which these lines are displayed is important, and I would like to preserve it. File2 is a data file with 456,000... (3 Replies)

mddiff
mddiff(1) Sync Mail Dir (smd) documentation mddiff(1)NAME
mddiff - computes diff for maildirs
SYNOPSIS
mddiff [--max-mailno mno] [--db-file dbf] [-l|--list] [-s|--symlink]
[--exclude globexpr] [-v|--verbose] [-d|--dry-run]
[-n|--no-delete] [--help] [--sha1sum] paths
DESCRIPTION
mddiff computes the delta from an old status of a maildir (previously recorded in a support file, called db file) and the current status,
generating a set of commands (a diff) that a third party software can apply to synchronize a (eventually remote) copy of the maildir.
If paths is a single file name, and that file is a fifo, mddiff reads from it file names separated by new line and outputs the sha1 of its
header and body separated by space.
$ mddiff /tmp/fifo_for_mddiff
806a0ffe4f29766effd764... 463e543da9dac8e298...
582cbb6a5cd3ce13965c8c... 8fa60a7458b1157193...
...
If paths is a single file name, and that file is a fifo, and the -s option is passed, mddiff reads from that fifo two lines at a time,
respectively a source name and a target name. It then creates a symlink named as as the target name pointing to the source name. If some
dictories need to be created in order to create the symlink, this is also done. mddiff will print 'OK' on stdout to signal a success,
'ERROR' to signal an error.
If paths is a list of directories, mddiff outputs a list of actions a client has to perform to synchronize a copy of the same maildirs.
This set of actions is relative to a previous status of the maildir stored in the db file. The input directories are traversed recur-
sively, and every file encountered inside directories named cur/ and new/ is a potential mail message (if it contains no
it is
skipped).
$ mddiff ~/Mail/
ADD ~/Mail/cur/1239038050.14937_1.garfield:2,S 66532ebb05b252e...
...
Every client (endpoint using mddiff for synchronization) must use a different db-file, and the db-file is strictly related with the set of
directories given as arguments, and should not be used with a different directory set. Adding items to the directory set is safe, while
removing them may not do what you want (delete actions are generated).
mddiff does not alter the dbf file, it generates a new one called dbf.new. It is up to the higher level tool smd-server(1) to rename
dbf.new to dbf in case the other endpoint successfully applied the diff.
The --exclude option tells mddiff to ignore all paths matching the given glob(7) expression. This option can be passed multiple times.
Matching is performed using fnmatch(3) with no special flags, thus '*' and '?' match any character including '/'. Matching is performed
when a directory is entered. If the match is successful, the directory and all its subedirectories are skipped.
The --no-delete option tells mddiff to not output a DELETE action for files that disappear. Note that a DELETE action is anyway generated
for files that are moved (i.e. move is COPY plus DELETE). The result is that deletions are not propagated to the other endpoint.
OPTIONS --max-mailno mno
Estimation of max mail message number (defaults to the number of messages in the db-file + 1000 or 500000 if there is no db-file).
You may want to decrease it for the first run on small systems. It is anyway increased automatically when needed
--db-file dbf
Name of the cache for the endpoint (default db.txt)
--exclude globexpr
Exclude paths maching the given expression
--sha1sum
Behaves like the sha1sum utility
--mkdir-p
Behaves like mkdir -p
--mkfifo
Behaves like mkfifo
-l --list
Only list the mailboxes recursively contained in paths
-s --symlink
Create symlinks for paths read on the input fifo
-v --verbose
Increase program verbosity (printed on stderr)
-d --dry-run
Do not generate a new db-file
-n --no-delete
Do not track deleted files
--help This help screen
NOTES
mddiff is a low level utility, used by smd-server and smd-client. You should use higher level tools like smd-pull(1), smd-push(1) and smd-
