./R1/new/svp950m01d.4gl
./R1/new/svp950m01g.4gl
./R1/new/svp955m01.4gl
./R1/new/svp960m01.4gl
./R1/new/svp965m01.4gl
./R1/new/svp992m06.4gl
./R1/new/svp994m01.4gl
./R1/new/svs402a.01.per
./R1/new/svs402a.03.per
./R1/new/svs402a.08.per
./R1/new/svs920a.01.per
./R1/new/svs920a.03.per
./R1/new/svs920a.08.per
./R1/old/sv_con.4gl
./R1/old/sv_gbl.4gl
./R1/old/sv_sosi_funcs.4gl
./R1/old/sva005a_en_CA.fgl
./R1/old/sva005a_en_US.fgl
./R1/old/sva005a_fr_CA.fgl
./R1/old/svm005a.fgl


i need to grep the lines with .per as extension

so the o/p wil be :::

./R1/new/svs402a.01.per
./R1/new/svs402a.03.per
./R1/new/svs402a.08.per
./R1/new/svs920a.01.per
./R1/new/svs920a.03.per
./R1/new/svs920a.08.per

And then i need to take the pattern

svs402a
svs402a
svs402a
svs920a
svs920a
svs920a

from the above results...

Kindly help me out in this!!!!!!!!!

hi aajan

#script test.sh
#!/bin/sh
grep svs <file_name> | cut -d/ -f4 | cut -c1-7

Use this command, it woks... for your above requirement

Code:

sed -n 's/.*\/\(svs[0-9]\{3\}a\).*\.per/\1/p' infile

you can as well type in at console


cat samplefile.txt|grep pattern | awk -F/ '{print $4}' | awk -F. '{print $1}'

out put would be ready.

Note: this works only if your files look like this ./R1/new/svs402a.01.per

cat oldfl|grep ".per"|awk -F/ '{print $4}'|awk -F. '{print $1}'
