Hi,
My ubuntu flavor always create temporary files having filename followed by ~ on editing. For eg: if I am editing a file called "sip.c", automatically a temporary (bkup) file is getting created with the name "sip.c~". How to avoid this file creation? (7 Replies)

Good afternoon.
I am a newbie.
We just had a potentially big problem (negated to having good backups).
Basically, there is an option in SAM, to delete all the data from the system that a user ever created.
Lo and behold, silly me, I choose that option, and all sorts of needed files... (5 Replies)

uniq
UNIQ(1) User Commands UNIQ(1)NAME
uniq - report or omit repeated lines
SYNOPSIS
uniq [OPTION]... [INPUT [OUTPUT]]
DESCRIPTION
Filter adjacent matching lines from INPUT (or standard input), writing to OUTPUT (or standard output).
With no options, matching lines are merged to the first occurrence.
Mandatory arguments to long options are mandatory for short options too.
-c, --count
prefix lines by the number of occurrences
-d, --repeated
only print duplicate lines, one for each group
-D print all duplicate lines
--all-repeated[=METHOD]
like -D, but allow separating groups with an empty line; METHOD={none(default),prepend,separate}
-f, --skip-fields=N
avoid comparing the first N fields
--group[=METHOD]
show all items, separating groups with an empty line; METHOD={separate(default),prepend,append,both}
-i, --ignore-case
ignore differences in case when comparing
-s, --skip-chars=N
avoid comparing the first N characters
-u, --unique
only print unique lines
-z, --zero-terminated
line delimiter is NUL, not newline
-w, --check-chars=N
compare no more than N characters in lines
--help display this help and exit
--version
output version information and exit
A field is a run of blanks (usually spaces and/or TABs), then non-blank characters. Fields are skipped before chars.
Note: 'uniq' does not detect repeated lines unless they are adjacent. You may want to sort the input first, or use 'sort -u' without
'uniq'. Also, comparisons honor the rules specified by 'LC_COLLATE'.
