How to insert a character in line in Special condition?
Hi,
I have a log file generated by a tool which has the following look :
/tmp/releases/directory/datefilename1_release_date.zip
/tmp/releases/directory/datefilename2_release_date.zip
/tmp/releases/directory/datefilename3_release_date.zip
/tmp/releases/directory/datefilename4_release_date.zip
Clearly you can identify the path generated for the each file by that tool is broken because there exists no "/" between date directory and the filename . I want to insert a "/" between the "date" and "filename" so that it becomes complete because this path is fed to another tool.
It should look like :
/tmp/releases/directory/date/filename1_release_date.zip
/tmp/releases/directory/date/filename2_release_date.zip
/tmp/releases/directory/date/filename3_release_date.zip
/tmp/releases/directory/date/filename4_release_date.zip
I tried with sed but did not know how to proceed. Please help . Thanks in advance.

GREP(1) General Commands Manual GREP(1)
NAME
grep - search a file for lines containing a given pattern
SYNOPSIS
grep [-elnsv] pattern [file] ...
OPTIONS
-e -e pattern is the same as pattern
-c Print a count of lines matched
-i Ignore case
-l Print file names, no lines
-n Print line numbers
-s Status only, no printed output
-v Select lines that do not match
EXAMPLES
grep mouse file # Find lines in file containing mouse
grep [0-9] file # Print lines containing a digit
DESCRIPTION
Grep searches one or more files (by default, stdin) and selects out all the lines that match the pattern. All the regular expressions
accepted by ed and mined are allowed. In addition, + can be used instead of * to mean 1 or more occurrences, ? can be used to mean 0 or 1
occurrences, and | can be used between two regular expressions to mean either one of them. Parentheses can be used for grouping. If a
match is found, exit status 0 is returned. If no match is found, exit status 1 is returned. If an error is detected, exit status 2 is
returned.
