simple awk script... - Shell Programming and Scripting

moxxx68 · #1 (**permalink**) 01-23-2005

hi everyone,
i have a script that I use regulary to look through my files and directories it works fine, but I would like to add a segment to the script to make the output more readable and userfriendly..
(i am not an expert on scripts so there is no comments or status exits as of yet..
)
#!/bin/bash
#.filer2
find $1 -type f -printf "%i\t%s %c %f\n" | egrep -v '(.date.*|foo|temp|file*)'| sort -n -r +1 | awk '($2 != 0)' | awk '{tot=i; i<=NR; i+=$2}END{print "Total="tot}{prin
t NR, $0}' | column -t

this is the script, the output is simply a listing plus a total of files greater than 0..

this is the directory tree

that is the output of the whole directory recrusivly..
now this is the output of the script:

5 270234 1283 Sun Jan 23 16:13:33 2005 Linux_distributions.loc
Total=8139

i would like to add title to each column .. like this
No. Inode Size Date Name
.................................................................................................... .....

i tried this but its not working too well..

#!/bin/bash
#.filer2
find $1 -type f -printf "%i\t%s %c %f\n" | egrep -v '(.date.*|foo|temp|file*)'| sort -n -r +1 | awk '($2 != 0)' | awk 'BEGIN{print $1, "No" $2, "Inode" $3, "Size" $7, "Date" $8, "Name\n""................................................................................\n"} {tot=i; i<=NR; i+=$2}END{print "Total="tot}{prin
t NR, $0}' | column -t

this does not seem to work the way that I am trying to get it to...
any feedback welcome
thanx moxxx68

I took your data

1 270199 2812 Sun Jan 23 16:13:33 2005 Gaining_skills.loc

5 270234 1283 Sun Jan 23 16:13:33 2005 Linux_distributions.loc

into file2

and did some thing like this.

Code:

awk '
BEGIN { printf("%2s %6s %4s %-24s %s\n","No","Inode","Size","Date","Name");
        printf("-----------------------------------------------------------\n"); }
{ print $0 }
' file2

this is what I tried amongst a few other combinations : no go!
can you give an example of the code?
here is what I have!
1 #!/bin/bash
2 #.filer2
3 find $1 -type f -printf "%i\t%s %c %f\n" | egrep -v '(.date.*|foo|temp|file*)'| sort -n -r +1 | awk '($2 != 0)' | awk '
4 BEGIN { printf("%2s %6s %4s %-24s %s\n","No","Inode","Size","Date","Name");
5 printf("-----------------------------------------------------------\n");}
6 {tot=i; i<=NR; i+=$2}END{print "Total="tot}{print NR, $0}' | column -t
edit:
this is what I keep getting anyway!
No Inode Size Date Name
