Full Discussion: shell script - search a file and perform some action

The script could look like:
Code:
#!/bin/bash

FILENAME=service.tra
S_PATH=/path/to/your/trace
D_PATH=/home/linus/gaurav

while :; do
   FOUND=$(find $S_PATH -type f -name "$FILENAME" -size +3000c -print)
   if [[ -n $FOUND ]]; then
      echo "File $FILENAME is larger than 3k - moving it."
      mv $FOUND $D_PATH
   fi
   sleep 3
done

exit 0

For infinite loops maybe put a sleep in there - else it might push your box to 100% CPU usage. In this example I use "find" but when the destination of the mv is also below this path, you'll get a problem, just as a site note. You might to use -purge in the find or check with ls -l or stat for the size of the file instead and check with -e if the file exists before that.

Code:
$one=`expr $one + 1`

Will not work since in a shell script there may be no spaces on the left or right of the equal sign. Also when declaring a variable there may be no $ in the name of the variable.

git-lost-found

GIT-LOST-FOUND(1)						    Git Manual							 GIT-LOST-FOUND(1)

NAME

       git-lost-found - Recover lost refs that luckily have not yet been pruned

SYNOPSIS

       git lost-found

DESCRIPTION

       NOTE: this command is deprecated. Use git-fsck(1) with the option --lost-found instead.

       Finds dangling commits and tags from the object database, and creates refs to them in the .git/lost-found/ directory. Commits and tags that
       dereference to commits are stored in .git/lost-found/commit, and other objects are stored in .git/lost-found/other.

OUTPUT

       Prints to standard output the object names and one-line descriptions of any commits or tags found.

EXAMPLE

       Suppose you run git tag -f and mistype the tag to overwrite. The ref to your tag is overwritten, but until you run git prune, the tag
       itself is still there.

	   $ git lost-found
	   [1ef2b196d909eed523d4f3c9bf54b78cdd6843c6] GIT 0.99.9c
	   ...

       Also you can use gitk to browse how any tags found relate to each other.

	   $ gitk $(cd .git/lost-found/commit && echo ??*)

       After making sure you know which the object is the tag you are looking for, you can reconnect it to your regular refs hierarchy by using
       the update-ref command.

	   $ git cat-file -t 1ef2b196
	   tag
	   $ git cat-file tag 1ef2b196
	   object fa41bbce8e38c67a218415de6cfa510c7e50032a
	   type commit
	   tag v0.99.9c
	   tagger Junio C Hamano <junkio@cox.net> 1131059594 -0800

	   GIT 0.99.9c

	   This contains the following changes from the "master" branch, since
	   ...
	   $ git update-ref refs/tags/not-lost-anymore 1ef2b196
	   $ git rev-parse not-lost-anymore
	   1ef2b196d909eed523d4f3c9bf54b78cdd6843c6
