Script needed

[Hunki]

We need to have script through which I can get a list of latest version numbers only ..like 1.20 along with the filename from which it comes.

The command which I use to get the version history is called "sccs prs filename"

Here is the example , it lists the latest version on the top and then then subsequent version below. I only need the latest version and the filename from the script and put it into an excel sheet for records.
-------------------------------------
$ sccs prs filename
filename

D 1.20 06/11/27 12:23:34 userid1 25 24 00012/00012/01066

D 1.19 06/10/12 08:21:45 userid1 24 23 00006/00006/01072

D 1.18 06/10/06 09:33:49 userid1 23 22 00004/00004/01074

try either:

sccs prs -d ":Dt:" -r

or

prs -d ":Dt:" -r

one of them should produce just the latest delta number of the filename specified.

man "prs" for more info

You can use this awk script:

$ sccs prs filename | awk '
BEGIN {
getline
filename = $0
getline; getline
VER = $2
print filename "," VER
exit 0
} '

For your above input, it prints:
filename,1.20

Thanks for the reply Dennis , what i have is multiple files instead of just one and they are under one parent directory , how to go about getting the info for each file.

Thanks,
hunki

Hunki,

#!/usr/bin/sh
for file in $(ls /path/to/dir)
do
sccs prs ${file} | awk -f prog.awk
done
exit

Sorry Spex its giving me problems running the script :

awk: can't open prog.awk
ERROR [SCCS/s.$(ls]: `SCCS/s.$(ls' nonexistent (ut4)
ERROR [/appl/solid/develop/SCCS/s.2006.3)]: `/appl/solid/develop/SCCS/s.2006.3)' nonexistent (ut4)

Sorry Spex its giving me problems running the script :

[Sandman!]

#!/usr/bin/sh

for i in $(ls -1 )
do
sccs prs $i | awk '!/^$/{if(x){x=x" "$2;print x;exit}else x=$0}'
done

./check_version.sh: syntax error at line 1 : `end of file' unexpected

>Sorry Spex its giving me problems running the script:

I assume Spex was pointing to my example awk script. Just put my fragment (without the trailing "'" in prog.awk.

[Hunki]

I ran it again Dennis but this is what I got :(

./check_version: syntax error at line 2: `$' unexpected

Hi Hunki,

do you work under HP-UX?
If not,
#!/usr/bin/sh
may not start a posix shell. Use
#!/usr/bin/ksh

instead.

[Dennis Handly]

As Peter asked, what is your shell and what is its absolute path?

>for file in $(ls /path/to/dir)

This is valid ksh or posix shell syntax and replaces the archaic ``. But it can be simplified to:
for file in path/to/dir/*; do

[Peter Godron]

Hi,
combining the pieces of code:

#!/usr/bin/sh
for file in `ls`
do
sccs prs $file | awk '
BEGIN {
getline
filename = $0
getline; getline
VER = $2
print filename "," VER
exit 0
}'
done

Please generate a shell script (a.sh) with the above. Then "chmod 744 a.sh". To run it "./a.sh"

[Hunki]

There are sub directories also which need to be looked into ( not only the parent dir ) and my shell is ksh.

parent dir : /appl/XXX/XXX/cur .... and there are subdirectories under it which need to be looked into.

Thanks,
hunki

Hi Hunki,

just change the way the filenames in question are determined:
Change
for file in `ls`
do
...
to something like this:
find YOUR_DIRNAMES -name SCCS -prune -type f -print | while read file
do
...
